PUSH-PULL FOUR CHANNEL DRIVER WITH DIODES
600mA OUTPUT CURRENT CAPABILITY
PER CHANNEL
1.2A PEAK OUTPUT CURRENT (non repeti-
tive) PER CHANNEL
ENABLE FACILITY
OVERTEMPERATURE PROTECTION
LOGICAL ”0” INPUT VOLTAGE UP TO 1.5 V
(HIGH NOISE IMMUNITY)
INTERNAL CLAMP DIODES
DESCRIPTION
The Device is a monolithic integrated high volt-
age, high current four channel driver designed to
accept standard DTL or TTL logic levels and drive
inductive loads (such as relays solenoides, DC
and stepping motors) and switching power tran-
sistors.
To simplify use as two bridges each pair of chan-
nels is equipped with an enable input. A separate
supply input is provided for the logic, allowing op-
eration at a lower voltage and internal clamp di-
odes are included.
This device is suitable for use in switching appli-
cations at frequencies up to 5 kHz.
