AT8236 Overview
The AT8236 from ZHONGKE MICROELECTRONICS is a high-performance single-channel H-bridge brushed DC motor driver built around integrated synchronous rectification technology to cut overall system power consumption significantly. Designed for bidirectional motor rotation and PWM-regulated speed adjustment, this IC embeds comprehensive built-in safety circuitry to guard against overcurrent, short-circuit, undervoltage and overheating damage during regular operation.
Housed in thermally optimised ESOP-8 packaging with exposed bonding pad for superior heat dissipation, ZHONGKE MICROELECTRONICS’s AT8236 splits into two variants: standard AT8236 with external VREF pin for custom current limiting and AT8236N featuring an open-drain nFAULT fault alert pin. It targets cost-sensitive mid-current BDC drive projects replacing expensive western-branded driver solutions across consumer and light industrial sectors.

Applications
The ZHONGKE MICROELECTRONICS AT8236 is deployed across office automation printers and peripheral devices, small domestic home appliances including water pumps and curtain motors, various smart home actuator systems, compact portable power tools, miniature factory automation actuators, low-power industrial valve drivers and small-sized battery-powered robotics assemblies needing bidirectional brushed DC motor control.
Pin-to-Pin Compatible Alternatives
Pin-to-pin drop-in compatible alternatives help OEM buyers optimise supply chain resilience and reduce component bill-of-material costs without costly PCB redesign when switching legacy western ICs to the cost-effective AT8236 driver from ZHONGKE MICROELECTRONICS.
| Reference Part Number | Original Manufacturer | Why Choose AT8236 |
|---|---|---|
| DRV8833 | Texas Instruments (TI) | Identical ESOP-8 footprint with lower unit pricing and improved sleep-mode power efficiency |
| TB6612FNG | Toshiba | Superior thermal performance thanks to exposed pad packaging and lower total RDS(on) resistance |
| A3906 | Allegro MicroSystems | Much reduced 20µA standby sleep current versus original part for battery-powered products |
