MAX14634_13 Datasheet, PDF (1/7 Pages) Maxim Integrated Products – Ultra-Low On-Resistance and Compact Bidirectional Battery Switch

EVALUATION KIT AVAILABLE
MAX14634
Ultra-Low On-Resistance and Compact
Bidirectional Battery Switch
General Description
The MAX14634 bidirectional battery switch features
reverse blocking capability to isolate the battery from the
system. The internal switch features ultra-low 7mI (typ)
on-resistance and operates from a +2.3V to +5.5V input
voltage range, making this device ideal as a battery-
disconnect switch for high-capacity battery applications.
The slew-rate controlled switch is also ideal for a large
load capacitor as well as high-current load switching
applications.
The device is available in an ultra-small 12-bump (1.3mm
x 1.7mm, 0.4mm pitch) WLP package. The tiny, low-
profile package is suitable for space-limited portable
device applications. The device operates over the -40NC
to +85NC extended temperature range.
