Circuit enables single NiMH cell to simulate a Lithium battery

Keywords:NiMH battery? power management? lithium-battery simulation?

Lithium-based 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 Lithium-based is therefore desirable, especially for smaller companies. This note describes a circuit that allows a nickel-metal hydride (NiMH) cell to be used in a circuit designed for a Lithium-based battery. It provides the same performance, size, and cost as a Lithium-based battery.
