1. TPIC0107B H-Bridge And DC Motor
Lucas Jessee
CENBD 452

2. Features Dedicated PWM Input Port
Optimized for Reversible Operation of Motors
Internal Current Shutdown of 5 A
40 V Load Dump Rating
CMOS Compatible Schmitt Trigger Inputs for High Noise Immunity

3. H-Bridge
It is mandatory that all four ground terminals plus at least one substrate terminal are connected to the system ground. Use all VCC and OUT terminals.
DIR controls Direction
PWM (Pulse Width Modulation) controls the motor’s speed.
OUT 1 and OUT 2 go to the motor.
STATUS 1 and STATUS 2 are for use with microcontrollers.

4. Internal Diagram Circuit Has Several Modes of Protection
Over Current/Short Circuit
Over Temperature
Under/Over Voltage
Cross Conduction
Open Circuit

5. Boring, but Important Note the unique Vcc Extreme temperature range
2 kHz Max PWM frequency

6. DC Motor Some DC motors have 4 wires, others have 2.
Motors with 2 wires are easy to control, just connect the two wires to OUT 1 and OUT 2.
Motors with 4 wires are easy as well. The Blue and Red wires are connected to OUT 1 and OUT 2, and the yellow and green wires aren’t used. They can be used to supply current through an internal generator.
The motor I ended up using has only 2 wires.

7. How I Hooked Up My Circuit
GNDS and GND all connected to ground.
Vcc all connected to 6 volts
DIR connected to push button
PWM connected to function generator
Status1 and Status2 are left open.
