Note:

1) Minimum and maximum limits are guaranteed by test, design, or statistical

correlation.Typical values represent the most likely parametric norm at TA = 25 °C, and are

provided for reference only.

2) Device thermal limitations could limit useful operating range.

3) he VC regulator is intended for internal use only as the startup supply of the PM8801; any

additional external VC current, including the VB regulator current and external MOSFET

driving current, has to be limited within the specified max current limit.
