Both bridges are capable of sustaining 45 V and include internal pulse-width modulation (PWM) control of the output current to 750 mA. The outputs have been optimized for a low output saturation voltage drop (less than 1.8 V total source plus sink at 500 mA). For PWM current control, the maximum output current is determined by user selection of a reference voltage and sensing resistor. Two logic-level inputs select output current limits of 0%, 33%, 67%, or 100% of the maximum level. A PHASE input to each bridge determines load current direction. Packages Package B 24-pin Batwing DIP The bridges include both ground-clamp and flyback diodes for protection against inductive transients. Internally generated delays prevent crossover currents when switching current direction. Special power-up sequencing is not required. Thermal protection circuitry disables the outputs if the chip temperature exceeds safe operating limits. Package LB 24-pin Batwing SOICW The device is supplied in a 24-pin dual in-line plastic (DIP, package B) with two pairs of batwing leads as heat-sinkable tabs for enhanced power dissipation capabilities.

Their webbed-lead construction provides for maximum package power dissipation in the smallest possible construction. The devices are available for operation from –20°C to 85°C (range N), and from –40°C to 105°C (range Q). All packages are lead (Pb) free, with 100% matte tin leadframe plating.
