L99MC6数据手册ST中文资料规格书

描述 Description

The L99MC6 IC is a highly flexible monolithic medium current output driver that incorporates 3 dedicated low-side outputs (channels 4 to 6) and 3 independently self configuring outputs (channels 1 to 3) that can be used as either low-side or high-side drivers in any combination. The L99MC6 can control inductive loads, incandescent bulbs or LEDs.

The L99MC6 can be used in a half bridge configuration with crosscurrent protection.

The channel 2 can be controlled directly via the IN/PWM pin for PWM applications. The IN/PWM signal can be applied to any other output.

The integrated 16-bit standard serial peripheral interface (SPI) controls all outputs and provides diagnostic information: normal operation, open-load in off-state, overcurrent, temperature warning, overtemperature.
