Note 1:

Internal current limited. 2.0 ms typical recovery time (RLBUS = 0

Ω, TX = 0.4 VREG, VLBUS = VBAT, TAMB =

25C. Recovery time highly dependent on ambient temperature, package and thermal resistance).

For design guidance only, not tested.

This current is at the VBAT pin.

The maximum power dissipation is a function of TJMAX,

ΘJA and ambient temperature TA. The maximum

allowable power dissipation at an ambient temperature is PD = (TJMAX - TA)

ΘJA. If this dissipation is

exceeded, the die temperature will rise above 150

°C and the MCP201 will go into thermal shutdown.
