Battery Switch with Four Enable Inputs
General Description
The MAX14525 features a low R ON 35m Ω (typ) load
switch with four unique enable inputs. The MAX14525
is ideal for disconnecting the lithium-ion (Li+) battery
from the loads in portable devices such as cell phones.
The MAX14525 operates from a +2.2V to +5.5V supply
voltage.
The MAX14525 features an extremely low 0.8μA (typ)
quiescent supply current to maximize battery life in
portable devices. It is enabled from four possible
inputs: external charger connection capable of high
voltage up to +28V, travel adapter (TA), on key (ON_K),
factory mode enable (JIG), and switch enable (S_EN).
The S_EN input is internally ANDed with the switched
battery connection (IN).
The MAX14525 is available in a small 8-pin, 2mm x
2mm TDFN package and operates over the -40°C to
+85°C extended temperature range.
