The ROHM single channel LED controller has high side current detection amplifier is built-in. PWM dimming duty can be freely set with built-in PWM generation circuit. PWM dimming realizes by driving an external P-ch MOSFET. Two systems of analogue dimming are built-in. High precision 3.0 V output power supply for analogue dimming and PWM dimming setting is built-in.
AEC-Q100 qualified Rail-to-Rail current sense amplifier Over voltage protection (OVP) Short circuit protection (SCP) DRL mode (100% Duty) enable Outputs abnormal LED status (FAULT_B) Spread spectrum frequency modulation ON/OFF
