Note 1: Attach a bypass capacitor to the Vs pin as required. Note 2: Utmost care is necessary in the design of the output line, VS, VCC and GND line since the IC may be destroyed by short-circuits between outputs, by supply faults, or by ground faults. Bear in mind also that mounting the IC in the reverse orientation may also cause a breakdown. Note 3: Switching the inputs may allow a pass-through current to flow. Keep the IC device in STOP mode (for at least 100 s) during the switching. Alternatively, insert a current-limiting resistor R. Note 4: Use a current-limiting resistor R or fuse for overcurrent protection. Note 5: When turning on the power for the IC device, apply VS after VCC (or VCC and VS simultaneously). When shutting off the power, drop VS before VCC (or Vs and VCC simultaneously). When turning on the power (VCC), keep both inputs (IN1 and IN2) on a low level.

Notes on Contents 1. Block Diagrams
Some of the functional blocks, circuits, or constants in the block diagrams 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 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 which must not be exceeded during operation, even for an instant. If any of these ratings are exceeded during operation, the device electrical characteristics may be irreparably altered and the reliability and lifetime of the device can no longer be guaranteed. Moreover, these operations with exceeded ratings may cause breakdown, damage and/or degradation to other equipment. Applications using the device should be designed so that each maximum rating will never be exceeded in 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, especially at the mass production design stage. Toshiba does not grant any license to any industrial property rights by providing these examples of application circuits.
6. Test Circuits
Components in the test circuits are only used to obtain and confirm the device characteristics. These components and circuits are not guaranteed to prevent malfunction or failure from occurring in the application equipment.
About the handling of ICs
Install the product correctly to avoid breakdown, damage and/or degradation to the product or equipment.
About over-current protection and heat protection circuits
These protection functions are intended to guard against certain output short circuits or other abnormal conditions with only temporary effect, and are not guaranteed to prevent the IC from being damaged. These protection features may not be effective if the product is operated outside the guaranteed operating ranges, and some output short circuits may result in the IC being damaged. The overcurrent protection feature is only intended to protect the IC from a temporary short circuit. Short circuits of longer duration may damage the IC through undue stress. The systems must be configured so that any overcurrent condition will be eliminated as soon as possible.

Counter-electromotive force
When the motor reverses or stops, counter-electromotive force in the motor may influence the current to flow to the power source. If the power source lacks sink capability, the IC power and output pins may exceed the rating. The counter-electromotive force of the motor varies depending on the conditions of use and the features of the motor. Therefore ensure that there is no damage to the IC or problem in operation, and no error in or damage to peripheral circuits resulting from counter-electromotive force.
