STMicroelectronics 12-channel LED Drivers
STMicroelectronics’ LED1202 programmable 12-channel LED driver enables smoother and natural lighting effects for smart-home devices, wearables, and small appliances.
The LED1202 features 12 low-side current generators, each capable of sinking 20mA and tight current matching between channels. The LED1202 can store 8 programmable patterns with 8-bit analog dimming control and 12-bit PWM resolution to create different patterns and lighting effects.
Multiple drivers can be used in applications requiring more than 12-channels, with two pins to set one of 8 I2C slave addresses, and a global address used to synchronize multiple drivers.
The LED1202 uses phase shifting to reduce inrush current and has open channel detection and overtemperature protection.
