Notes:
1. Exceeding the maximum rating may damage the device.
2. Devices are ESD sensitive. Handling precautions recommended.
3. The device is not designed to function outside its operating rating.
4. Off is
≤0.8V and on is ≥2.4V for the RYC82x0-1 and RYC82x0-3. Off is ≥2.4V and on is ≤0.8V for the RYC82x0-2 and RYC82x0-4.
The enable input has approximately 200mV of hysteresis. Pull-down/pull-up resistors are on chip for “-1” and “-2” configurations.
5. With internal enable pull up/down resistors.
6. Pull-up resistors are on chip.
7. No error flag output delay on UVLO, OVLO and thermal shut down.
