IC LED DRV LIN PWM 16ETSSOP Output Linear Constant Current PWM Dimming Optoelectronic IC

PRODUCT DESCRIPTION

The IS32LT3124 is a linear programmable current regulator consisting of 4 output channels capable of up to 150mA each. Individual external resistors set the maximum current level for each channel. The outputs can be combined to provide a higher current drive capability up to 600mA (Max.).

The IS32LT3124 features Dynamic Headroom Control (DHC) with an optional external PMOS FET to minimize IC thermal stress when the supply voltage exceeds the LED string forward voltage. It includes two modes for different output power: Shunt Regulator mode and Series Regulator mode. It can operate with power supply modulation (PSM) for applications requiring dimming without use of the EN pin.

For added system reliability, the IS32LT3124 integrates fault detection circuitry for open/short circuit and over temperature conditions. The fault pins (FLTB) can all be tied together to disable the device and other IS32LT3124 devices on the same parallel circuit.

To handle all these different fault detection and reporting features, the IS32LT3124 has six different versions: A, B, C, D, E and F. All of them can support the above features. See table 1 for the major difference.

In IS32LT3124A/B/D/E, if any fault condition occurs, all output currents will be disabled. In IS32LT3124B/C/E/F, individual ISET pin for each LED channel is redefined as individual PWM dimming control, thus ISET open detection function is removed. The EN pin of IS32LT3124B/C/E/F is featured as the enable signal of the internal fault reporting block. See Table 4 for complete fault listing.

The IS32LT3124 is targeted at the automotive market such as interior accent lighting and exterior tail lighting. It is offered in a thermally enhanced eTSSOP-16 package.
