00 — Overview

What the AT8236 does

The AT8236 is a single-channel DC brushed motor driver chip handling 6A peak current. It operates across a 5.5V to 36V supply range with 200mΩ on-resistance and 100kHz PWM control. The device features integrated synchronous rectification, internal protections like overcurrent and thermal shutdown, and a fault detection output. Available in ESOP8 packages, it supports low-power sleep modes. Engineers typically use this component in printers, home appliances, smart home systems, and industrial control applications where precise bidirectional motor speed regulation is required.
