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
