Notes:
4. RL = 100Ω connected to ground.
5. RL = 10Ω connected to ground.
6. Delay from commanding Hi-Z or 0V to beginning slope. Does not apply to current limit or overtemperature shutdown conditions.
7. The MIC2562A uses VCC3 IN for operation. For single 5V supply systems, connect 5V to both VCC3 IN and VCC5 IN. See “Applications Information”
section for further details.
8. VPP IN is not required for operation.
9. VPP IN must be either high impedance or greater than or approximately equal to the highest voltage VCC in the system. For example, if both 3.3V
and 5V are connected to the MIC2562A, VPP IN must be either 5V, 12V, or high impedance.
10. A 10kΩ pull-up resistor is connected between FLAG and VCC3 IN.
