Output Operation

•

Control mode selection

Either constant-current or direct PWM control can be selected by the Vref input voltage as follows:

Constant-current PWM control: Vref = 0 to 3 V

Direct PWM control: Vref = 4.5 V to VREG

The constant-current feature is disabled in direct PWM mode.

In either mode, the motor operating mode changes between CW/CCW and short brake alternately.

To eliminate shoot-through current that flows from supply to ground due to the simultaneous conduction of

high-side and low-side transistors in the bridge output, a dead time of 300 ns (design target value) is generated

in the IC when transistors switch from on to off, or vice versa.

The shoot-through protection permits a synchronous rectification PWM operation without controlling the dead

time externally. A dead time is also provided internally when the motor operation mode switches between CW

and CCW, and between CW (CCW) and short brake, thereby eliminating the need for external dead time

insertion.

Constant-Current Regulation

When the V voltage is kept constant, the constant current regulator keeps the output current constant by

ref

using a peak current detection technique.

(1) Constant-current chopping

When V reaches the reference voltage (Vref), the regulator enters Discharge mode.

RS

After four cycles of CK, an internal clock generated by OSC, the regulator moves from Discharge mode

to Charge mode.

(2) Changing the predefined current (during deceleration)

When VRS reaches the reference voltage (Vref/6), the regulator enters Discharge mode. Four CK cycles

later, the regulator exits Discharge mode and enters Charge mode. If VRS > Vref/6 when it enters

Charge mode, however, it then reenters Discharge mode. Four CK cycles later, VRS is again compared

against Vref/6. If VRS < Vref/6, the regulator enters and remains in Charge mode until VRS reaches

Vref/6.

The average current value becomes lower than the set current value because of the peak current detection

method. It should be noted that the average current value changes, depending on the motor characteristics.

Calculation of the Internal Oscillation Frequency

The OSC oscillation frequency can be calculated by the following equation:

fosc = 1/{0.523 × (Cosc [F] × 3700 + Cosc [F] × 600)} [Hz]

•

The TB6559FG includes a 5-V power supply for control circuit biasing.

For oscillation prevention, a capacitor should be connected between VREG and S-GND.

Although VRGE can be used to control the inputs to the TB6559FG, the maximum load current should be

limited to 1 mA.

•

The TB6559FG has power monitoring circuitry that turns off the output when VREG falls below 6.0 V

(design target value). With a hysteresis of 0.3 V (design target value), the output is turned back on when

VREG reaches 6.3 V (design target value) again.

GND Section

•

The TB6559FG has two separate grounds: S-GND for the control circuitry and P-GND for the output

circuitry. S-GND and P-GND should be short-circuited at a location as close to the TB6559FG as possible.

ALERT Circuit

•

When either the thermal shutdown or overcurrent protection circuit is activated, the ALERT output goes

High (CMOS output). ALERT may be initially unstable causing chattering or noise pulses. To avoid such

instability, it is recommended to insert an RC filter to the output line.

Normal: Low

Protective operation: High

Thermal Shutdown (TSD) Circuit

The TB6559FG incorporates a thermal shutdown circuit. When the junction temperature (T ) exceeds

j

160°C (typ.), the output transistors are turned off.

The output transistors are automatically turned on when the junction temperature cools past the shutdown

threshold, which is lowered by a hysteresis of 40°C.

The IC has 40°C of temperature hysteresis.

ALERT output

The TB6559FG allows for the sensing of the current that flows through each output transistor.

The currents through each of the output transistors are continually monitored. In the event of an overcurrent

in at least one of the transistors, the overcurrent protection circuitry turns all transistors off.

The overcurrent protection circuitry incorporates a timer to measure 50 μs (typ.) after the transistors are

turned off. After 50 μs, the protection circuitry turns the output transistors back on again automatically. If the

overcurrent persists, the device begins cycling into and out of thermal shutdown. To prevent false detection due

to glitches, the overcurrent protection circuitry turns off the transistors only when the current exceeds the

shutdown threshold for 10 μs or longer.

The design target value for current limiting is 5.0 A (typ.) but has variations between 4.0 to 6.0 A.

Usage Precautions

•

Although the TB6559FG contains overcurrent detection circuitry, a large current might abruptly flow through

the IC in case of a short-circuit to power supply, a short-circuit to ground or a short-circuit across the load,

damaging the device permanently. This possibility should be fully considered in the design of the output, V

and ground lines. If the device is damaged, a large current might continually flow through the device as a

secondary effect. Therefore, Toshiba recommends that a fuse be connected to the power supply line.

CC

•

Install this IC properly. If not, (e.g., installing it in the wrong position), the IC might be broken.

If external components are shorted together, the IC might be broken.

IC Usage Considerations

Notes on Handling of ICs

(1) The absolute maximum ratings of a semiconductor device are a set of ratings that must not be

exceeded, even for a moment. Do not exceed any of these ratings.

Exceeding the rating(s) may cause the device breakdown, damage or deterioration, and may result

injury by explosion or combustion.

(2) Use an appropriate power supply fuse to ensure that a large current does not continuously flow in case

of over current and/or IC failure. The IC will fully break down when used under conditions that exceed

its absolute maximum ratings, when the wiring is routed improperly or when an abnormal pulse noise

occurs from the wiring or load, causing a large current to continuously flow and the breakdown can

lead smoke or ignition. To minimize the effects of the flow of a large current in case of breakdown,

appropriate settings, such as fuse capacity, fusing time and insertion circuit location, are required.

(3) If your design includes an inductive load such as a motor coil, incorporate a protection circuit into the

design to prevent device malfunction or breakdown caused by the current resulting from the inrush

current at power ON or the negative current resulting from the back electromotive force at power OFF.

IC breakdown may cause injury, smoke or ignition.

Use a stable power supply with ICs with built-in protection functions. If the power supply is unstable,

the protection function may not operate, causing IC breakdown. IC breakdown may cause injury,

smoke or ignition.

(4) Do not insert devices in the wrong orientation or incorrectly.

Make sure that the positive and negative terminals of power supplies are connected properly.

Otherwise, the current or power consumption may exceed the absolute maximum rating, and

exceeding the rating(s) may cause the device breakdown, damage or deterioration, and may result

injury by explosion or combustion.

In addition, do not use any device that is applied the current with inserting in the wrong orientation or

incorrectly even just one time.

TB6559FG

Points to Remember on Handling of ICs

(1) Over Current Protection Circuit

Over current protection circuits (referred to as current limiter circuits) do not necessarily protect ICs

under all circumstances. If the Over current protection circuits operate against the over current, clear

the over current status immediately.

Depending on the method of use and usage conditions, such as exceeding absolute maximum ratings

can cause the over current protection circuit to not operate properly or IC breakdown before operation.

In addition, depending on the method of use and usage conditions, if over current continues to flow for

a long time after operation, the IC may generate heat resulting in breakdown.

(2) Thermal Shutdown Circuit

Thermal shutdown circuits do not necessarily protect ICs under all circumstances. If the thermal

shutdown circuits operate against the over temperature, clear the heat generation status immediately.

Depending on the method of use and usage conditions, such as exceeding absolute maximum ratings

can cause the thermal shutdown circuit to not operate properly or IC breakdown before operation.

(3) Heat Radiation Design

In using an IC with large current flow such as power amp, regulator or driver, please design the device

so that heat is appropriately radiated, not to exceed the specified junction temperature (T ) at any time

j

and condition. These ICs generate heat even during normal use. An inadequate IC heat radiation

design can lead to decrease in IC life, deterioration of IC characteristics or IC breakdown. In addition,

please design the device taking into considerate the effect of IC heat radiation with peripheral

components.

(4) Back-EMF

When a motor rotates in the reverse direction, stops or slows down abruptly, a current flow back to the

motor’s power supply due to the effect of back-EMF. If the current sink capability of the power supply

is small, the device’s motor power supply and output pins might be exposed to conditions beyond

maximum ratings. To avoid this problem, take the effect of back-EMF into consideration in system

design.
