Universal H-Bridge Driver
Hardware Design
Revision 1.0
- Dual MOSFET complementary H-Bridge outputs (3A current per channel) provided by ZXMHC3F381N8 ICs, gates driven with pullup resistors and NPN darlingtons
- AVR XMEGA D4 microcontroller
- Two full-H outputs, one combined 4-channel output for a bipolar stepper motor, 2 servo motor outputs (replaces second H output)
- 2 analog inputs
- 2 TTL/servo inputs
- input voltage monitor (UVLO, battery discharge protection)
- 3.3V UART
Revision 1.2
- Freescale MC33887 integrated 5A bridge/driver with all N-channel MOSFETS (one for each full bridge)
- Dedicated TTL PWM channels
- 5V-tolerant Schmitt triggers on TTL/servo inputs (74LVC2G14)
- ESD suppression on logic inputs/outputs
Applications
- PWM lamp dimmer (2 or 4 channels with external ground)
- Reversibe DC motor driver (2 channels)
- Bipolar stepper motor driver
- Servo motor controller (2 channels)
- Servo amp (2 channels with PWM input or 1 channel with analog input)
- Brushless DC motor driver

Notes
- JP1 is for using servo input power supply to power the outputs, must be left unpopulated when using a separate supply.
- J13 is for programming the AVR microcontroller, standard ISP/PDI pinout as used by Atmel tools.
