Master大大,

3.1 Charge Enable Input (CE)
A logic High enables battery charging. A logic Low
disables battery charging. The charge enable input is
compatible with 1.8V logic.

3.5 Current Regulation Set (PROG)
For the MCP73811, the current regulation set input
(PROG) functions as a digital input selection. A logic
Low selects a 85 mA charge current; a logic High
selects a 450 mA charge current.
For the MCP73812, the charge current is set by placing
a resistor from PROG to VSS.

看datasheet跟你形容得不太一樣喔,PROG好像是用來選擇charge current大小的,不會不工作,除非是你Charge Enable Input (CE)接錯電位,你要看清楚喔!
