ELECTRICAL CHARACTERISTICS - NOTES
Note 1.
Exceeding the absolute maximum rating may damage the device.
Note 2.
Devices are ESD sensitive. Handling precautions recommended..
Note 3.
The device is not designed to function outside its operating rating.
Note 4.
Off is
≤
0.8V and on is
≥
2.4V for the RYC8220-1 and RYC8220-3. Off is
≥
2.4V and on is
≤
0.8V for the RYC8220-2 and RYC8220-4. The
enable input has approximately 200mV of hysteresis. Pull-down/Pull-up resistors are on chip for “-1” and “-2” configurations.
Note 5.
Pull-up resistors are on chip.
Note 6.
No error flag out delay on UVLO, OVLO and thermal shutdown.
