NAME
FUNCTION
Shutdown. A high logic level turns on the device. When SHDN is low the part is off,
and the current into BATT is typically 0.1μA. For the MAX1832/MAX1833, the

SHDN
battery is connected to OUT through an internal PFET and the external inductor
when SHDN is low. SHDN can be used for low-battery cutoff (1.228V threshold).
See Low-Battery Cutoff . SHDN has reverse battery protection.
