Renesas Electronics Corporation Power Supply Controllers, Monitors ISL6121LIBZA-T

The ISL6121LIBZA-T is a single supply integrated current limiting controller designed for applications requiring overcurrent protection. It operates within a voltage range of 2.5V to 5.5V and features a 0.05Oc integrated N-channel MOSFET switch, allowing for efficient power control. The device includes accurate current sensing and limiting capabilities, with a maximum output current of 2A. It incorporates a 12ms timed fault latch-off feature that is independent of temperature, ensuring reliable operation under varying conditions. The controller also provides an under voltage lockout function, which prevents output activation unless the input voltage exceeds 2.5V. The enable input can be configured for either high or low logic levels, and the fault output signal is compatible with standard logic levels, facilitating external monitoring and control. The ISL6121LIBZA-T is RoHS compliant and available in an 8-lead SOIC package, making it suitable for a variety of applications, including industrial power control and hot plug scenarios.
