L292
SWITCH-MODE DRIVER FOR DC MOTORS
DRIVING CAPABILITY : 2 A, 36 V, 30 KHz
2 LOGIC CHIP ENABLE
EXTERNAL LOOP GAIN ADJUSTEMENT
SINGLE POWER SUPPLY (18 TO 36 V)
INPUT SIGNAL SYMMETRIC TO GROUND
THERMAL PROTECTION
DESCRIPTION
The L292 is a monolithic LSI circuit in 15-lead
Multiwatt ® package. It is intended for use, together
with L290 and L291, as a complete 3-chip motor
positioning system for applications such as car-
riage/daisy-wheel position control in type-writes.
The L290/1/2 system can be directly controlled by
a microprocessor.

The enable inputs were implemented in this way
because they are intended to be driven directly by
a microprocessor. Currently available microproces-
sors may generates spikes as high as 1.5 V during
power-up. These inputs may be used for a variety
of applications such as motor inhibit during reset of
the logical system and power-on reset (see fig. 3).
