T63H0008A
Description
The T63H0008A series are lithium-ion/lithium polymer rechargeable battery protection ICs incorporating high-accuracy voltage detection circuit and delay circuit. The T63H0008A series are suitable for protection of single-cell lithium ion/lithium polymer battery packs from overcharge, over-discharge and over-current and 0V battery charge function.
Key Features
- 1: Overcharge release voltage = Overcharge detection voltage - Overcharge hysteresis voltage (where overcharge release voltage<3.8V is prohibited.) *2: Over-discharge release voltage = Over-discharge detection voltage + Over-discharge hysteresis voltage (where over-discharge release voltage>3.4V is prohibited.) l Delay times (overcharge: tVDET1, over-discharge: tVDET2, over-current 1: tVDET3, over-current 2: t VDET4) are generated by an internal circuit. No external capacitor is necessary. …………….Accuracy: ±20% l Three-step over-current detection circuit is included. (over-current 1, over-current 2, and load short-circuiting). l Either charge function or charge inhibition function for 0V battery can be selected. l Charger detection function and abnormal charge current detection function 1.The over-discharge hysteresis is released by detecting negative voltage at the V- pin (-0.7V typ.). (Charger detection function) 2.When the output voltage of the DOUT pin is high and the voltage at the V- pin is equal to or lower than the charger detection voltage (-0.7V typ.), the output voltage of the COUT pin goes low. (Abnormal charge current detection function) l Low current consumption . 1.Operation 3.0uA typ. 7.0uA max.(IDD). 2.Power -down 0.1 uA max.(ISB). l Wide operating temperature range: -40ºC to +85ºC l Ultra Small package …………………..SOT-23-6 (6 PIN),SNB(B)(6PIN).
