APPLICATION NOTE 3744
Circuit Enables Single NiMH Cell to Simulate a Lithium Battery

Abstract: This circuit uses a NiMH cell to replace a lithium battery. Its output simulates the discharge characteristic
of a lithium (Li+) battery.


Introduction

Lithium-based (Li+) batteries are becoming common in portable equipment. They have desirable characteristics, but
they are often in short supply. Lead times can be long unless you have a preferred-customer status with the battery
manufacturer. A backup alternative to Li+ is therefore desirable, especially for smaller companies. This note describes
a circuit
