DUAL-BRIDGE DRIVER IC FOR DC MOTORS

The TB6592FL/FLG is a dual-bridge driver IC for DC motors

with output transistors in an LD MOS structure with low

ON-resistance. Two input signals, IN1 and IN2, can be used to

select one of four modes such as CW, CCW, short brake, and stop

mode. A PWM drive system supports high heat efficiency

driving.

Operating Description

•

PWM control function

Speed can be controlled by inputting the high-level or low-level PWM signal to the pin PWM.

When PWM control is provided, normal operation and short brake operation are repeated.

To prevent penetrating current, dead time (t2 and t4) is provided in the IC.

Requests Concerning Use of QON

Outline Drawing of Package

Upper surface

Lower surface

When using QON, take into account the following items.

Caution

(1) Do not carry out soldering on the island sections in the four corners of the package (indicated by the

hatched sections in the figure for the lower surface, above left) with the aim of increasing mechanical

strength.

(2) The projecting island sections on the package surfaces (indicated by the hatched sections in the

figures for the upper and lower surfaces above) must be electrically insulated from outside when used.

Note: Ensure that the island sections (indicated by the hatched sections in the figure for the lower surface,

above left) do not come into contact with solder from through-holes on the board layout.

•

When mounting or soldering, take care to ensure that neither static electricity nor electrical

overstress is applied to the IC. (Measures to prevent electrostatic discharge, leaks, etc.)

When incorporating the IC into a set, adopt a set design that does not apply voltage directly to the

island section.

Notes on contents

1. Block Diagrams

Some of the functional blocks, circuits, or constants in the block diagram may be omitted or simplified for

explanatory purposes.

2. Equivalent Circuits

The equivalent circuit diagrams may be simplified or some parts of them may be omitted for explanatory

purposes.

3. Timing Charts

Timing charts may be simplified for explanatory purposes.

4. Maximum Ratings

The absolute maximum ratings of a semiconductor device are a set of specified parameter values that must not

be exceeded during operation, even for an instant.

If any of these ratings are exceeded during operation, the electrical characteristics of the device may be

irreparably altered, in which case the reliability and lifetime of the device can no longer be guaranteed.

Moreover, any exceeding of the ratings during operation may cause breakdown, damage and/or degradation in

other equipment. Applications using the device should be designed so that no maximum rating will ever be

exceeded under any operating conditions.

Before using, creating and/or producing designs, refer to and comply with the precautions and conditions set

forth in this document.

5. Application Circuits

The application circuits shown in this document are provided for reference purposes only. Thorough evaluation

is required in the mass production design phase.

In furnishing these examples of application circuits, Toshiba does not grant the use of any industrial property

rights.

6. Test Circuits

Components in test circuits are used only to obtain and confirm device characteristics. These components and

circuits are not guaranteed to prevent malfunction or failure in application equipment.

Handling of the IC

Ensure that the product is installed correctly to prevent breakdown, damage and/or degradation in the product

or equipment.

Over-current protection and heat protection circuits

These protection functions are intended only as a temporary means of preventing output short circuits or other

abnormal conditions and are not guaranteed to prevent damage to the IC.

If the guaranteed operating ranges of this product are exceeded, these protection features may not operate

and some output short circuits may result in the IC being damaged.

The over-current protection feature is intended to protect the IC from temporary short circuits only.

Short circuits persisting over long periods may cause excessive stress and damage the IC. Systems should

be configured so that any over-current condition will be eliminated as soon as possible.

Counter-electromotive force

When the motor reverses or stops, the effect of counter-electromotive force may cause the current to flow to the

power source.

If the power supply is not equipped with sink capability, the power and output pins may exceed the maximum

rating.

The counter-electromotive force of the motor will vary depending on the conditions of use and the features of

the motor. Therefore make sure there will be no damage to or operational problem in the IC, and no damage to

or operational errors in peripheral circuits caused by counter-electromotive force.
