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.
