XD754410 DIP16 1 Features 3 Description The XD754410 is a quadruple high-current half-H 1 1-A Output-Current Capability Per Driver driver designed to provide bidirectional drive currents Applications Include Half-H and Full-H Solenoid up to 1 A at voltages from 4.5 V to 36 V. The device Drivers and Motor Drivers is designed to drive inductive loads such as relays, Designed for Positive-Supply Applications solenoids, DC and bipolar stepping motors, as well as other high-current/high-voltage loads in positive- Wide Supply-Voltage Range of 4.5 V to 36 V supply applications. TTL- and CMOS-Compatible High-Impedance All inputs are compatible with TTL-and low-level Diode-Clamped Inputs CMOS logic. Each output (Y) is a complete totem- Separate Input-Logic Supply pole driver with a Darlington transistor sink and a Thermal Shutdown pseudo-Darlington source. Drivers are enabled in Internal ESD Protection pairs with drivers 1 and 2 enabled by 1,2EN and drivers 3 and 4 enabled by 3,4EN. When an enable Input Hysteresis Improves Noise Immunity input is high, the associated drivers are enabled and 3-State Outputs their outputs become active and in phase with their Minimized Power Dissipation inputs. When the enable input is low, those drivers are disabled and their outputs are off and in a high- Sink/Source Interlock Circuitry Prevents impedance state. With the proper data inputs, each Simultaneous Conduction pair of drivers form a full-H (or bridge) reversible drive No Output Glitch During Power Up or Power suitable for solenoid or motor applications. Down A separate supply voltage (V ) is provided for the CC1 logic input circuits to minimize device power dissipation. Supply voltage V is used for the output CC2 circuits. 2 Applications The XD754410 is designed for operation from 40C Stepper Motor Drivers to 85C.
