L2293QTR

Full Half-Bridge (H Bridge) Drivers Overview

The L2293QTR is a monolithic integrated high voltage, high current four-channel driver designed to accept standard DTL or TTL logic levels. It drives inductive loads such as relays, solenoids, DC and stepping motors, and switching power transistors. The device features internal clamp diodes and an enable facility for each pair of channels to simplify bridge configurations. A separate supply input allows logic operation at lower voltages. It supports switching applications up to 50 kHz and includes overtemperature protection.
