LM18298 Dual Full-Bridge Driver
General Description
The LM18298 is a high voltage high current dual full-bridge
driver designed to accept standard TTL logic levels and
drive inductive loads such as relays solenoids DC and
stepping motors Two enable inputs are provided to gate the
input control signals
The emitters of the lower transistors of each bridge are con-
nected together and the corresponding external terminal
can be used for the connection of a current sensing resistor
An additional supply input is provided to accommodate con-
ventional logic supply voltages
Features
Y Power supply voltage up to 46V
Y 2A output per channel
Y Low saturation voltage
Y Thermal shutdown protection
Y Logical ‘‘0’’ input voltage up to 1 5V
(High noise immunity)
Y Pin for pin replacement for L298N
Applications
Y DC and stepper motor drivers
Y Relay and solenoid drivers
