Block Diagram
Absolute Maximum Ratings
The CS3750 is a dual H-bridge four
quadrant air-core gauge driver. The IC
provides all the functions necessary to
drive a tachometer or speedometer as
part of a microprocessor based multi-
plexed system. Digital input control
eliminates the need for any analog cali-
bration of the gauge.
The controlling microprocessor sends
out a PWM signal to each H bridge
driver input (IN1, IN2). The PWM sig-
nal duty cycle is proportional to the
HDbridge output. Output current
(100mA max) direction is controlled by
the DIRECTION input. PWM switch-
ing noise is minimized at each half
bridge by an internal RC filter and
external programmable capacitor.
The CS3750 is protected against 50V
load dump, over voltage and thermal
runaway fault conditions. Any of these
faults causes the IC to shut down. Each
high side of the output driver is current
limited. A short circuit condition in one
driver does not affect the others.
