Innovative Electronics EMS 30 A H-Bridge User Manual

EMS (Embedded Module Series)
30 A H-Bridge rev. 1
Embedded Module Series (EMS) 30 A H-
Bridge is a VNH3SP30 based H-Bridge driver
designed to generate 2 ways drive with continuous current
up to 30 A at 5.5 Volts to 36 Volts voltage (up to 16 V
for IC VNH2SP30). This module is equipped with a current
sensor that can be used as a feedback to the controller.
This module can drive inductive loads such as relay,
solenoid, DC motor, motor stepper, and other kinds of
load.
Specifications
1. Consists of 1 full H-Bridge driver. A current sense
circuitry for IC VNH2SP30 is available.
2. Can pass 30 A continuous current.
3. Load voltage ranges from 5.5 V to 36 V (up to 16 V
for IC VNH2SP30).
4. Compatible with TTL and CMOS level input.
5. Power supply input for the driver (VCC) is separated
from power supply input for the loads (V Mot).
6. Tri-state output.
7. PWM frequency up to 20 KHz.
8. Fault Detection.
9. Short circuit protection.
10. Overtemperature protection.
11. Undervotage and Overvoltage Shutdown.
12. Reverse Battery Protection.

If there is a faulty condition
(thermal shutdown,
undervoltage, overvoltage,
etc.), then this pin will be
pulled low internally by H-
Bridge module to report the
faulty condition

Enable pin for MOUT2 output
Give High logic to activate
half H-Bridge 2, give Low
logic externally to deactivate
half H-Bridge 2
If there is a faulty condition
(thermal shutdown,
undervoltage, overvoltage,
etc.), then this pin will be
pulled low internally by H-
Bridge module to report the
