STMicroelectronics LED1642GWXTTR Gate Driver, 40 mA, 3 → 5.5V 24-Pin, TSSOP24

The STMicroelectronics LED driver, it is a monolithic, low voltage and low current power 16-bit shift register designed for LED panel displays. The LED1642GW guarantees 20 V output driving capability allowing the user to connect several LEDs in series. In the output stage, sixteen regulated current sources provide from 3 mA to 40 mA constant current to drive the LEDs.

Current programmable through external resistor
Error detection mode
Thermal shutdown and over temperature alert
