OUTLINE

The RN5VM Series are protection ICs for over-charge/discharge of rechargeable one-cell Lithium-ion (Li+) batteries by CMOS process.

The RN5VM Series can detect over-charge/discharge of Li+ one-cell and excess load current, further include a short circuit protector for preventing large external short circuit current.

FEATURES

• Low supply current ................................Supply current TYP. 3.0µA

Standby current (after detecting over-discharge) TYP. 0.3µA

• High withstand voltage..........................Absolute maximum ratings 28V (VDD–V-)

• High accuracy detector threshold .......Over-charge detector ±50mV

Over-discharge detector ±2.5

• Variety of detector threshold................Over-charge detector threshold 4.0V to 4.4V/step of 0.01V

Over-discharge detector threshold 2.0V to 3.0V/step of 0.05V

• Built-in protection circuit.......................Excess current trip/Short circuit protector

• Output delay of over-charge .................Time delay at C3= 0.01µF and VDD=4.3V 75ms for RN5VM111×

• Ultra small package ...............................SOT-23-6

APPLICATIONS

• Over-charge/over-discharge protection for Li+ one-cell pack

• High precision protectors for cell-phones and any other gadgets using on board Li+ one-cell battery
