MP2702 - 1A Linear Charger

General Description

The MP2702 is a linear charger for 1-cell to 2cell Li-ion, Li-polymer, and LiFePO4, and 2-cell to 6-cell NiMH batteries.

The device can sustain a voltage up to 26V.

Key Features

  • including input and battery over-voltage protection (OVP), a charge safety timer, and battery temperature protection compliant with the JEITA standard. -------- The MP2702 provides a dedicated EN pin to enable or disable charging. Once charging is disabled, the quiescent current (IQ) flowing into either the IN or BATT pin is minimized. In addition, the MP2702 provides two opendrain pins to indicate the input power status and ---------------- charge status. The ACOK pin indicates whether --------.

MP2702 1-Cell to 2-Cell, 26V Input, 1A Linear Charger with EN Control and Configurable JEITA DESCRIPTION The MP2702 is a linear charger for 1-cell to 2cell Li-ion, Li-polymer, and LiFePO4, and 2-cell to 6-cell NiMH batteries. The device can sustain a voltage up to 26V. The MP2702 measures the battery voltage (VBATT) and automatically charges the battery in four phases: trickle charge, pre-charge, constant-current (CC) fast charge, and constant-voltage charge. The MP2702 provides a dedicated ISET pin to set the charge current by connecting a resistor between ISET and ground. The device also provides a USBM pin to set the input current limit (IIN_LIM) prior to setting the charge current.
