Cost-Saving Multichemistry
Battery-Charger System
_______________General Description
____________________________Features
The MAX846A is a cost-saving multichemistry battery-
charger system that comes in a space-saving 16-pin
QSOP. This integrated system allows different battery
chemistries (Li-Ion, NiMH or NiCd cells) to be charged
using one circuit.

Multichemistry Charger System (Li-Ion, NiMH, NiCd)
Independent Voltage and Current Loops
±0.5% Internal Reference for Li-Ion Cells
Lowers Cost:
In its simplest application, the MAX846A is a stand-
alone, current-limited float voltage source that charges
Li-Ion cells. It can also be paired up with a low-cost
microcontroller (μC) to build a universal charger capa-
ble of charging Li-Ion, NiMH, and NiCd cells.
An internal 0.5%-accurate reference allows safe charg-
ing of Li-Ion cells that require tight voltage accuracy.
The voltage- and current-regulation loops used to con-
trol a low-cost external PNP transistor (or P-channel
MOSFET) are independent of each other, allowing more
flexibility in the charging algorithms.
The MAX846A has a built-in 1%, 3.3V, 20mA linear regu-
lator capable of powering the μC and providing a refer-
ence for the μC ’s analog-to-digital converters. An
on-board reset notifies the controller upon any unex-

pected loss of power. The μC can be inexpensive, since
its only functions are to monitor the voltage and current
and to change the charging algorithms.
