Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

Description:

The L99UDL01 is an integrated 6-way half-bridge output chip that is PWM and current adjustable and can be configured with up to two external half-bridges for higher current requirements. Diagnostics include load open circuit, short-circuit power supply, ground-to-ground short-circuit, and load current feedback via 10-bit SPI.

The L99UDL01 can be configured with switching time and current by SPI.

Features:

Meets AEC-Q100 standard

Six integrated fully protected 0.09Ω half-bridges

Integrated half-bridges can be completely independent or paralleled by up to three
