Product Description

PT2484A Overview

The PT2484/PT2484A is a dual-channel H-bridge motor driver featuring a wide operating voltage range, supporting a supply voltage from 4V to 16V. Equipped with four independent control logic pins, it offers flexible operation and can drive 4-wire bipolar stepper motors, two brushed DC motors, or electromagnetic loads.
The PT2484A integrates built-in protection circuits, which can effectively prevent the H-bridge driver from being damaged due to short-circuit or over-temperature conditions.
