TPIC0107B H-Bridge And DC Motor Lucas Jessee ljj116@psu.edu CENBD 452

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

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.

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

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

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.

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.
