However, by any possibility, we would request user fail-safe design and post-aging treatment on system or equipment.
The XC6221 series’ fold-back circuit operates as an output current limiter and a short protection circuit for the output pin.
When the load current reaches the current limit level, the fixed current limiter circuit operates and output voltage drops.

internal pull-down resistor. However, the CE input current will be increased via a pull-down resistor when the IC
operates. If this IC is used with the correct output voltage for the CE pin, the logic is fixed and the IC will operate
normally. However, the supply current may increase as a result of shoot-through current in the IC's internal circuitry
