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

Pin Name I/O Function
1 MIN1 I Input pin to determine the
MOU 1 output
2 MIN2 I Input pin to determine the
MOU 2 output
3 MEN1 I/O
Enable pin for MOU 1 output
Give High logic to activate
half H-Bridge 1, give Low
logic externally to deactivate
half H-Bridge 1
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
4 MEN2 I/O
Enable pin for MOU 2 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
faulty condition

esting Procedure
-Connect the power supply source for input (VCC) and
the power supply for load (V Mot)
-Perform testing by giving a High logic (+5V) or Low
(0V) to the input (MIN1, MIN2, MEN1, MEN2, and
MPWM) that matches the truth table
-Output terminals (MOU 1 and MOU 2) will produce
output voltage that matches the functions stated in the
truth table
