ABSOLUTE MAXIMUM RATINGS

at TA = +25°C Load Supply Voltage, VBB ................ 50 V Output Current, IOUT Transient (<500 ns) ................... ±5 A Logic Supply Voltage, VDD ............................................ 7.0 V Sense Voltage, VSENSE ...................... 0.5 V Logic Input Voltage Range, VIN .................. -0.3 V to VDD + 0.3 V High-Side Gate Voltage ........... VBB + 8 V Package Power Dissipation, PD ............................................. 2.2 W Operating Temperature Range, TA ............................. -20°C to +85°C Junction Temperature, TJ ............. +150°C Storage Temperature Range, TS ........................... -55°C to +150°C Output duty cycle, ambient temperature, and heat sinking may limit current rating. Under any set of conditions, do not exceed the specified current rating or a junction temperature of 150 °C. DUAL DMOS FULL-BRIDGE DRIVER Designed to interface between external PWM control logic and inductive loads such as relays, solenoids, dc motors, or stepper motors, each full bridge can operate with output currents to ±2.5 A and operating voltages to 50 V.
