L99MC6 Configurable 6-channel device Features 3 independently self configuring high-/low-side channels 3 low-side channels R =0.7 (typ) at T = 25 C ON j Current limit of each output at min. 0.6 A PWM direct mode PowerSSO-16 Bulb mode with recovery mode LED mode with slew rate control Description Bridge mode with crosscurrent protection The L99MC6 IC is a highly flexible monolithic SPI interface for data communication medium current output driver that incorporates 3 Temperature warning dedicated low-side outputs (channels 4 to 6) and All outputs overtemperature protected 3 independently self configuring outputs (channels 1 to 3) that can be used as either low- All outputs short-circuit protected side or high-side drivers in any combination. The Configurable open-load detection in off mode L99MC6 can control inductive loads, V supply voltage 3.0 V to 5.25 V incandescent bulbs or LEDs. CC Very low current consumption in standby mode The L99MC6 can be used in a half bridge 5A (typ) configuration with crosscurrent protection. Internal clamp diodes The channel 2 can be controlled directly via the HS switches operate down to 3 V crank voltage IN/PWM pin for PWM applications. The IN/PWM signal can be applied to any other output. Applications The integrated 16-bit standard serial peripheral interface (SPI) controls all outputs and provides Relay driver diagnostic information: normal operation, open- LED driver load in off-state, overcurrent, temperature warning, overtemperature.
