MP2724GRH-0000-P

Overview

The MP2724GRH-0000-P is a single-cell lithium-ion or lithium-polymer battery charger IC from Monolithic Power Systems. It features an I2C-controlled switch-mode buck architecture with a maximum charging current of 2.2A and a battery pack voltage up to 4.6V. The device operates on a supply voltage range of 3.9V to 6.3V, drawing up to 3.2A during operation. It supports programmable charge current, timer, and voltage settings, along with comprehensive fault protection including overcurrent, overtemperature, overvoltage, and short-circuit safeguards. The component is housed in a 22-QFN (2.5x3.5mm) package and functions within a junction temperature range of -40°C to +125°C.

Procurement Notes

Verify the specific suffix 'P' against the manufacturer's official datasheet to confirm it denotes the standard tape-and-reel packaging format. Ensure the ordering part number matches the exact QFN-22 variant required for your PCB footprint. Cross-reference the RoHS compliance status and MSL rating with the latest production data before finalizing procurement orders.

Selection Notes

Select this component when a compact, high-efficiency solution for single-cell batteries is required. The I2C control allows for dynamic adjustment of charging parameters via software. Consider the 2.2A output capability and 6.3V input range relative to your system's power budget and thermal constraints in the QFN-22 package.
