Product Description

The MP6420 provides over-charge protection that integrates a protective, open-drain MOSFET for 2- or 3-series cell Li-ion power systems.

The MP6420 provides a ±25mV, high-accuracy, over-charge threshold to monitor all series’ battery pack conditions. With the high-accuracy threshold, the MP6420 can provide different fixed thresholds from 4.2V to 4.8V internally. Any cell over-charge that occurs turns on the internal protective MOSFET to indicate an error after an internally set, fixed delay time.

The MP6420 is available in a small, space-saving TSOT23-8 package.

Battery Protection IC for 2-/3-Series Cell Li-Ion with Protective MOSFET and PTC Interface

The EV6420-J-00A is an evaluation board for the MP6420.

The MP6420 provides overcharge protection that integrates a protective, open-drain MOSFET for 2- or 3-series cell Li-ion power systems.

The MP6420 provides a ±15mV, high-accuracy, overcharge threshold to monitor all series’ battery pack conditions. With the high-accuracy threshold, the MP6420 can provide different fixed thresholds from 4.2V to 4.8V internally. Any cell overcharge that occurs turns on the internal protective MOSFET to indicate the error after an internally set, fixed delay time.

The MP6420 is available in a small, space-saving TSOT23-8 package.
