1 / 8 page Preliminary RT9541 DS9541-05 August 2001 www.richtek-ic.com.tw 1 Li-Ion Battery Protector General Description The RT9541 Series are protection ICs for over- charge/discharge of rechargeable one-cell Lithium-ion (Li+) batteries by CMOS process. The RT9541 Series can detect over-charge/discharge of Li+ one-cell and excess load current and charge current, further include a short circuit protector for preventing large external short circuit current. Each of these ICs is composed of four voltage detectors, a reference unit, a hysteresis circuit, and a bidirectional short circuit protector. Package of SOT- 26 is available. Ordering Information RT9541 Typical Application Circuit Features Low supply current − Supply current: TYP. 2.0µµµµA − Standby current (after detecting over- discharge): Less than 0.2 µµµµA High accuracy detector threshold − Over-charge detector: ±±±±25mV − Over-discharge detector: ±±±±2.5% Built-in protection circuit − Excess current trip/Short circuit protector in both charging and discharging direction Output delay of over-charge adjustable with an external capacitor: 75mS at 0.01 µµµµF Ultra small package: SOT26 Applications Over-charge / Over-discharge Protection for Li+ One-cell Pack High Precision Protectors for Cellular Phones or Instruments Using Li+ One-cell Battery Pin Configurations Part Number Pin Configurations RT9541 CE (Plastic SOT-26) TOP VIEW 1.
