Note 1: Internal current limited. 2.0 ms typical recovery time (RLBUS = 0Ω, TX = 0.4 VREG, VLBUS = VBAT, TAMB =
25C. Recovery time highly dependent on ambient temperature, package and thermal resistance).
2: For design guidance only, not tested.
3: This current is at the VBAT pin.
4: 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.
