Notes:
4. R

= 100Ω connected to ground.
5. R
L
= 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 V
CC3
IN for operation. For single 5V supply systems, connect 5V to both V
CC3
IN and V
CC5
IN. See “Applications Information”
section for further details.
8. V
PP
IN is not required for operation.
9. V
PP
IN must be either high impedance or greater than or approximately equal to the highest voltage V
CC
in the system. For example, if both 3.3V
and 5V are connected to the MIC2562A, V
PP
IN must be either 5V, 12V, or high impedance.
10. A 10kΩ pull-up resistor is connected between FLAG and V
CC3
IN.
