Overview
NXP Semiconductors Technical Data 5.
0 A H-Bridge The 34931 is a monolithic H-Bridge Power IC in a robust thermally enhanced package.
It is designed for any low voltage DC servo motor control application within the current and voltage limits stated in this specification.
This device is powered by SMARTMOS technology.
The 34931 H-Bridge is able to control inductive loads with currents up to 5.
0 A peak.
RMS current capability is subject to the degree of heatsinking provided to the device package.
Internal peak current limiting (regulation) is activated at load currents above 6.
5 A ±1.
5 A.
Output loads can be pulse-width modulated (PWMed at frequencies up to 20 kHz.
A load current feedback feature provides a proportional (0.
24% of the load current) current output suitable for monitoring by a microcontroller’s A/D input.
A status flag output reports undervoltage, overcurrent, and overtemperature fault conditions.
Two independent inputs provide polarity control of two half-bridge totem-pole outputs.
The disable inputs are provided to force the H-Bridge outputs to tri-state (high-impedance off-state).
