NCP382LD15AAGEVB

Fixed Current-Limiting Power-Distribution Switches NCP382 The NCP382 is a single input dual outputs high side powerdistribution switch designed for applications where heavy www.onsemi.com capacitive loads and shortcircuits are likely to be encountered. The device includes an integrated 80 m , P channel MOSFET. The MARKING device limits the output current to a desired level by switching into a DIAGRAM constantcurrent mode when the output load exceeds the currentlimit 8 threshold or a short is present. The currentlimit threshold is internally 8 XXXXXX fixed. The powerswitches rise and fall times are controlled to ALYWX 1 minimize current ringing during switching. SOIC8 NB The FLAG logic output asserts low during overcurrent or 1 CASE 751 overtemperature conditions. The switch is controlled by a logic enable input active high or low.

Pin Connections PIN FUNCTION DESCRIPTION Pin Name Type Description EN1 I Enable 1 input, logic low/high (i.e. EN or EN) turns on power switch. EN2 I Enable 2 input, logic low/high (i.e. EN or EN) turns on power switch. GND P Ground connection. IN P Powerswitch input voltage connect a 1 F or greater ceramic capacitor from IN to GND as close as possible to the IC. FLAG1 O Activelow opendrain output 1, asserted during overcurrent or overtemperature conditions. Connect a 10 k or greater resistor pullup, otherwise leave unconnected. FLAG2 O Activelow opendrain output 2, asserted during overcurrent or overtemperature conditions. Connect a 10 k or greater resistor pullup, otherwise leave unconnected. OUT1 O Powerswitch output1 connect a 1 F ceramic capacitor from OUT1 to GND, as close as possible to the IC. This minimum value is recommended for USB requirement in terms of load transient response and strong short circuits. OUT2 O Powerswitch output2 connect a 1 F ceramic capacitor from OUT2 to GND, as close as possible to the IC. This minimum value is recommended for USB requirement in terms of load transient response and strong short circuits. www.onsemi.com 2
