IS32LT3140A SINGLE CHANNEL 450mA LED DRIVER

The IS32LT3140A is an automotive-grade high-side programmable current regulator consisting of a single output channel capable of 450mA. An external resistor sets the current level for the single-channel current source. An optional thermal shunt resistor can be used to significantly optimize IC power.

IS32LT3140A Features

* an EN pin to enable or shutdown the device. It supports either PWM dimming via a PWM pin or power supply modulation (PSM). A resistor divider circuit can be used on the UV pin to set an external VCC under-voltage lockout threshold for LED string open and single LED short fault detection. In addition
