Advance Information
5.2 A H-Bridge with Load Current
Feedback
The 33887 is a monolithic H-Bridge Power IC with a load current feedback
feature making it ideal for closed-loop DC motor control. The IC incorporates
internal control logic, charge pump, gate drive, and low RDS(ON) MOSFET
output circuitry. The 33887 is able to control inductive loads with continuous
DC load currents up to 5.2 A, and with peak-current active-limiting between 6.0
and 8.5 A. Output loads can be pulse width modulated (PWM-ed) at
frequencies up to 20 kHz. The load current feedback feature provides a
proportional (1/375th of the load current) constant-current output suitable for
monitoring by a microcontroller’s A/D input. This feature facilitates the design
of closed-loop torque control.
A Fault Status output reports undervoltage, overcurrent, and
overtemperature conditions. Two independent inputs provide polarity control
of two half-bridge totem-pole outputs. Two disable inputs force the H-Bridge
outputs to tristate (exhibiting high impedance).
The 33887 is parametrically specified over a temperature range of -40
°C ≤
TA ≤ 125°C and a voltage range of 5.0 V ≤ VPWR ≤ 28 V. The IC can also be
operated for short periods of time at 150
°C and up to 36 V with derating of the
specifications.
