Battery Switch with Four Enable Inputs

MAX1425

General Description

Features

The MAX14525 features a low R

35mΩ (typ) load

♦ Low 35mΩ (typ) R

Load Switch

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.

♦ Ultra Low, 0.8µA (typ) Supply Current

♦ Four Enable Inputs:

TA: +28V (max) Capable

ON_K: Accurate +3V Trigger Enable

JIG: Factory Mode Enable

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).

S_EN: Logically ANDed with IN

♦ Space-Saving 8-Pin, 2mm x 2mm TDFN Package

♦ Controlled Turn-On to Limit dI/dt Pulses Due to

Lead Inductance

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.
