DC Brush Motor Drivers (36V max.)

BD623xxx Series

●General Description

●Key Specifications

These H-bridge drivers are full bridge drivers for brush

motor applications. Each IC can operate at a wide range

of power supply voltages (from 6V to 32V), with output

currents of up to 2A. MOS transistors in the output stage

allow PWM speed control. The integrated VREF voltage

control function allows direct replacement of deprecated

motor driver ICs. These highly efficient H-bridge driver

ICs facilitate low-power consumption design.

a) Stand-by mode

Stand-by operates independently with the VREF pin voltage. In stand-by mode, all internal circuits are turned off,

including the output power transistors. Motor output goes to high impedance. When the system is switched to

stand-by mode while the motor is running, the system enters an idling state because of the body diodes. However,

when the system switches to stand-by from any other mode (except the brake mode), the control logic remains in the

high state for at least 50µs before shutting down all circuits.

b) Forward mode

This operating mode is defined as the forward rotation of the motor when the OUT1 pin is high and OUT2 pin is low.

When the motor is connected between the OUT1 and OUT2 pins, the current flows from OUT1 to OUT2. To operate

in this mode, connect the VREF pin to the VCC pin.

c) Reverse mode

This operating mode is defined as the reverse rotation of the motor when the OUT1 pin is low and OUT2 pin is high.

When the motor is connected between the OUT1 and OUT2 pins, the current flows from OUT2 to OUT1. To operate

in this mode, connect the VREF pin to the VCC pin.

d) Brake mode

This operating mode is used to quickly stop the motor (short circuit brake). It differs from the stand-by mode because

the internal control circuit is operating in the brake mode. Please switch to stand-by mode (rather than the brake

mode) to save power and reduce consumption.

e) f) PWM control mode A

The rotational speed of the motor can be controlled by the duty cycle of the PWM signal fed to the FIN pin or the

RIN pin. In this mode, the high side output is fixed and the low side output is switching, corresponding to the input

signal. The state of the output toggles between "L" and "Hi-Z".

The frequency of the input PWM signal can be between 20kHz and 100kHz. The circuit may not operate properly for

PWM frequencies below 20kHz and above 100kHz. Note that control may not be attained by switching on duty at

frequencies lower than 20kHz, since the operation functions via the stand-by mode. To operate in this mode,

connect the VREF pin to the VCC pin. In addition, establish a current path for the recovery current from the motor,

by connecting a bypass capacitor (10µF or higher is recommended) between VCC and ground.

i) j) VREF control mode

The built-in VREF duty cycle conversion circuit provides a duty cycle corresponding to the voltage of the VREF pin

and the VCC voltage. The function offers the same level of control as the high voltage output setting function in

previous models. The duty cycle is calculated by the following equation.

DUTY ≈ VREF [V] / VCC [V]

For example, if VCC voltage is 24V and VREF pin voltage is 18V, the duty cycle is about 75 percent. However,

please note that the duty cycle might be limited by the range of the VREF pin voltage (Refer to the operating

conditions, shown on page 2). The PWM carrier frequency in this mode is 25kHz (nominal), and the switching

operation is the same as the PWM control modes. When operating in this mode, do not input a PWM signal to the

FIN and RIN pins. In addition, establish a current path for the recovery current from the motor, by connecting a

bypass capacitor (10µF or more is recommended) between VCC and ground.

2) Cross-conduction protection circuit

In the full bridge output stage, when the upper and lower transistors are turned on at the same time during high to low

or low to high transition, an inrush current flows from the power supply to ground, resulting to a loss. This circuit

eliminates the inrush current by providing a dead time (about 400ns, nominal) during the transition.

3) Output protection circuits

a) Under voltage lock out (UVLO) circuit

To ensure the lowest power supply voltage necessary to operate the controller, and to prevent under voltage

malfunctions, a UVLO circuit has been built into this driver. When the power supply voltage falls to 5.0V (nominal) or

below, the controller forces all driver outputs to high impedance. When the voltage rises to 5.5V (nominal) or above,

the UVLO circuit ends the lockout operation and returns the chip to normal operation.

b) Over voltage protection (OVP) circuit

When the power supply voltage exceeds 45V (nominal), the controller forces all driver outputs to high impedance.

The OVP circuit is released and its operation ends when the voltage drops back to 40V (nominal) or below. This

protection circuit does not work in the stand-by mode. Also, note that this circuit is supplementary, and thus if it is

asserted, the absolute maximum rating will have been exceeded. Therefore, do not continue to use the IC after this

circuit is activated, and do not operate the IC in an environment where activation of the circuit is assumed.

c) Thermal shutdown (TSD) circuit

The TSD circuit operates when the junction temperature of the driver exceeds the preset temperature (175℃

nominal). At this time, the controller forces all driver outputs to high impedance. Since thermal hysteresis is provided

in the TSD circuit, the chip returns to normal operation when the junction temperature falls below the preset

temperature (150℃ nominal). Thus, it is a self-resetting circuit.

The TSD circuit is designed only to shut the IC off to prevent thermal runaway. It is not designed to protect the IC or

guarantee its operation in the presence of extreme heat. Do not continue to use the IC after the TSD circuit is

activated, and do not operate the IC in an environment where activation of the circuit is assumed.

d) Over current protection (OCP) circuit

To protect this driver IC from ground faults, power supply line faults and load short circuits, the OCP circuit monitors

the output current for the circuit’s monitoring time (10µs, nominal). When the protection circuit detects an over

current, the controller forces all driver outputs to high impedance during the off time (290µs, nominal). The IC returns

to normal operation after the off time period has elapsed (self-returning type). At the two channels type, this circuit

works independently for each channel.

●Operational Notes

1) Absolute maximum ratings

Operating the IC over the absolute maximum ratings may damage the IC. The damage can either be a short circuit

between pins or an open circuit between pins. Therefore, it is important to consider circuit protection measures, such

as adding a fuse, in case the IC is operated over the absolute maximum ratings.

2) Reverse connection of power supply

Connecting the power supply in reverse polarity can damage the IC. Take precautions against reverse

polarity when connecting the power supply, such as mounting an external diode between the power

supply and the IC’s power supply terminals.

3) Power supply lines

Design the PCB layout pattern to provide low impedance ground and supply lines. Separate the ground and supply

lines of the digital and analog blocks to prevent noise in the ground and supply lines of the digital block from affecting

the analog block. Furthermore, connect a capacitor to ground at all power supply pins. Consider the effect of

temperature and aging on the capacitance value when using electrolytic capacitors.

4) Ground Voltage

The voltage of the ground pin must be the lowest voltage of all pins of the IC at all operating conditions. Ensure that no

pins are at a voltage below the ground pin at any time, even during transient condition.

5) Thermal consideration

Use a thermal design that allows for a sufficient margin by taking into account the permissible power dissipation (Pd) in

actual operating conditions. Consider Pc that does not exceed Pd in actual operating conditions (Pc≥Pd).

Package Power dissipation

Power dissipation

: Pd (W)=(Tjmax－Ta)/θja

: Pc (W)=(Vcc－Vo)×Io+Vcc×Ib

Tjmax : Maximum junction temperature=150℃, Ta : Peripheral temperature[℃] ,

θja : Thermal resistance of package-ambience[℃/W], Pd : Package Power dissipation [W],

Pc : Power dissipation [W], Vcc : Input Voltage, Vo : Output Voltage, Io : Load, Ib : Bias Current

6) Short between pins and mounting errors

Be careful when mounting the IC on printed circuit boards. The IC may be damaged if it is mounted in a

wrong orientation or if pins are shorted together. Short circuit may be caused by conductive particles

caught between the pins.

7) Operation under strong electromagnetic field

Operating the IC in the presence of a strong electromagnetic field may cause the IC to malfunction.

8) Area of Safe Operation (ASO)

Operate the IC such that the output voltage, output current, and power dissipation are all within the Area of Safe

Operation (ASO).

9) Capacitor between output and GND

If a large capacitor is connected between the output pin and GND pin, current from the charged capacitor can flow into

the output pin and may destroy the IC when the VCC or VIN pin is shorted to ground or pulled down to 0V. Use a

capacitor smaller than 10uF between output and GND.

10) Testing on application boards

When testing the IC on an application board, connecting a capacitor directly to a low-impedance output pin may subject

the IC to stress. Always discharge capacitors completely after each process or step. The IC’s power supply should

always be turned off completely before connecting or removing it from the test setup during the inspection process. To

prevent damage from static discharge, ground the IC during assembly and use similar precautions during transport and

storage.

11) Switching noise

When the operation mode is in PWM control or VREF control, PWM switching noise may affect the control input pins

and cause IC malfunctions. In this case, insert a pull down resistor (10kꢀ is recommended) between each control input

pin and ground.

12) Regarding the input pin of the IC

This monolithic IC contains P+ isolation and P substrate layers between adjacent elements in order to keep them

isolated. P-N junctions are formed at the intersection of the P layers with the N layers of other elements, creating a

parasitic diode or transistor. For example (refer to figure below):

When GND > Pin A and GND > Pin B, the P-N junction operates as a parasitic diode.

When GND > Pin B, the P-N junction operates as a parasitic transistor.

Parasitic diodes inevitably occur in the structure of the IC. The operation of parasitic diodes can result in mutual

interference among circuits, operational faults, or physical damage. Therefore, conditions that cause these diodes to

operate, such as applying a voltage lower than the GND voltage to an input pin (and thus to the P substrate) should be

avoided.
