Overview
The TPIC6273DWR is a monolithic high-voltage, high-current power logic octal D-type latch produced by Texas Instruments. This device is designed for use in systems that require relatively high load power, featuring eight power DMOS transistor outputs. Each output is capable of handling 250 mA of continuous current and up to 1.5 A of pulsed current. The TPIC6273DWR includes a built-in voltage clamp on the outputs for inductive transient protection, making it suitable for driving relays, solenoids, and other medium-current or high-voltage loads.
