CS2516

Pulse-Load Battery Monitor

Description

Features

The CS2516 is designed for use in bat-

external transistor can be added to in-

crease the load current capability.

Adjustable Battery Sense

from 7 to 12 Volts

■

tery powered medical, security, or

environmental systems where prior

notification of impending power

source failure is a requirement. The IC

effectively provides continuous moni-

toring of battery condition by pulse-

sampling the system voltage at prede-

termined intervals. Low standby cur-

rent permits unswitched connection to

the battery with minimal impact on

operating life. The ability to load the

battery during the test pulse provides

assurance that sufficient reserve capac-

ity exists to operate critical system

components.

Should, during the test pulse, the sense

terminal voltage fall below the thresh-

old level determined by the internal

(synthesized) temperature compensat-

ed zener diode, the comparator will

permit a charging current to flow out

of PW. This pin is also the input of a

Schmitt trigger that in turn drives the

output transistor. Collectively, the

charge current and trigger, in conjunc-

tion with an external RC network,

operate as a Òpulse-stretcherÓ to pro-

vide output ÒONÓ times that are a

multiple of the sampling time. This

feature permits low battery alarm

devices or visible annunciators to be

driven directly by the IC. The maxi-

mum permissible output current is

30mA.

Pulse Loads Battery at up

to 50mA

Standby Current Under

10µA

■ Test Period, Rate and Load

Adjustable

■ On Chip 15mA Output

Driver

The CS2516 contains an internal timer

that generates a 1.0 millisecond test

pulse once each 33 seconds (both times

are typical). The load switch transistor

conducts only during the test pulse,

and can sink up to 50mA directly. An
