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.
