Features, Applications

The S-8201 Series are lithium-ion/lithium polymer rechargeable battery protection ICs incorporating highaccuracy voltage detection circuit and delay circuit. The S-8201 Series are suitable for protection of singlecell lithium ion/lithium polymer battery packs from overcharge, overdischarge and overcurrent.

Features

(1) Internal high accuracy voltage detection circuit Overcharge detection voltage (5 mV step), Accuracy mV (+25 C), to +55 C) *1 Overcharge release voltage V , Accuracy 50mV Overdischarge detection voltage (10 mV step), Accuracy mV *2 Overdischarge release voltage V , Accuracy 100 mV Overcurrent 1 detection voltage (10 mV step) Accuracy 15 mV Overcurrent 2 detection voltage 0.5 V (fixed) Accuracy mV (2) High voltage device is used for charger connection pins. (VM pin and CO pin: Absolute maximum V) (3) Delay times (Overcharge: tCU, Overdischarge: tDL, Overcurrent 1: tlOV1, Overcurrent 2: tlOV2) are generated by an internal circuit. (No external capacitor is necessary.) Accuracy 20% (4) The overcharge timer reset delay time to 40 ms) is generated by an internal circuit only. (No external capacitor is necessary.) (5) Three-step overcurrent detection circuit is included. (Overcurrent 1, Overcurrent 2, Load short-circuiting) (6) Either charge function or charge inhibition function for 0 V battery can be selected. (7) Charger detection function and abnormal charge current detection function The overdischarge hysteresis is released by detecting negative voltage at the VM pin (-0.7 V typ.). (Charger detection function) When the output voltage of the DO pin is high and the voltage at the VM pin is equal to or lower than the charger detection voltage (-0.7 V typ.), the output voltage of the CO pin goes low. (Abnormal charge current detection function) (8) Low current consumption Operation 3.5 A typ., 7.0 A max. Power-down 0.1 A max. (9) Wide operating temperature range +85C (10) Small package SOT-23-6, 6-Pin SNB(B) *1. The overcharge hysteresis voltage V or can be selected from the range 50 mV step. Overcharge hysterests voltage (VHC)=Overcharge detection voltage-Overcharge release voltage *2. The overdischarge hysteresis voltage V or can be selected from the range 100 mV step. Overdischarge hysteresis voltage (VHD)=Overdischarge release voltage-Overdischarge detection voltage
