DUAL H-BRIDGE DRIVER
■GENERAL DESCRIPTION
■PACKAGE OUTLINE
NJM2672 is a dual H-bridge driver, it consists of a LS-TTL
compatible logic input stage and pair of H-bridges with a
protection diode. The maximum output current is 500mA per
channel.
NJM2672 is able to make up pulse input stepper motor
system when using with translator NJU7380.
