Overview
DATASHEET ISL6121 Single Supply Integrated Current Limiting Controller The ISL6121 is a single supply Overcurrent (OC) fault protection IC for 2.
5V to 5V applications where 2A current limiting is desired.
This device features internal current monitoring and limiting along with a 50m integrated power switch and a current limited time out to latch-off feature for system protection.
The time to latch-off is independent of device temperature, and magnitude of OC.
Each ISL6121 incorporates in a 8 lead SOIC package a 50m N-channel MOSFET power switch for power control.
The switch is driven by a constant current source giving a controlled ramp up of the output voltage.
This provides a soft start turn-on eliminating bus voltage drooping caused by inrush current while charging heavy load capacitances.
(Enable high (ISL6121H) and enable low (ISL6121L) options are) available with a fault reporting output compatible with 3V and 5V logic level signals allowing for external control and monit...
