DC DC Cntrlr Triple-OUT 8-Pin SOIC N
The ISL6121 is a single supply Overcurrent (OC) faultprotection IC for 2.5V to 5V applications where 2A currentlimiting is desired. This device features internal currentmonitoring and limiting along with a 50mΩ integrated powerswitch and a current limited time out to latch-off feature forsystem protection. The time to latch-off is independent ofdevice temperature, and magnitude of OC. Each ISL6121 incorporates in a 8 lead SOIC package a50mΩ N-channel MOSFET power switch for power control.The switch is driven by a constant current source giving acontrolled ramp up of the output voltage. This provides a softstart turn-on eliminating bus voltage drooping caused by inrushcurrent while charging heavy load capacitances.(Enable high (ISL6121H) and enable low (ISL6121L) optionsare) available with a fault reporting output compatible with 3Vand 5V logic level signals allowing for external control andmonitoring.
