Battery Manager
General Description
The MAX1259 battery manager provides backup-battery
switching for CMOS RAM, microprocessors, or other
low-power logic ICs. It automatically switches to the
backup battery when the primary power supply is inter-
rupted. Low-loss switches guarantee an input-to-output
differential of only 200mV while supplying 250mA from
the primary power supply or 15mA from the battery.
Battery discharge during shipping does not occur in the
MAX1259, since the backup battery can be disconnect-
ed by strobing the RST input.
A battery-fail output signal indicates when the backup
battery is below +2V, and a power-fail output signal indi-
cates when the primary power supply is low. The
MAX1259 monitors the backup battery, warns of
impending power failures, and switches the memory to
the battery when failures occur. The MAX1259 is pin-
Features
? Switches to Backup Battery if Power Fails
? Consumes Less than 100nA of Battery Current
? Power-Fail Output Signals Primary
Power-Supply Loss
? Battery Monitor Indicates Low Battery
? Battery Can Be Disconnected to Prevent
Discharge During Shipping
? Battery Automatically Reconnected when
V CC is Applied
? Pin-Compatible with the DS1259
? Supply Current Three Times Lower than DS1259
? Available in Extended-Industrial and Military
Temperature Ranges
Ordering Information
compatible with the DS1259, but consumes three times
less supply current. Commercial, extended, and military
temperature range devices are available.
