Revision:A or VDET2, over-discharge condition can be also released. An output delay time for the over-discharge detection is fixed internally, tVDET2 =10ms typ. At VDD=2.4V. When the VDD level is going down to a lower level than VDET2 if the VDD voltage would be back to a level higher than the VDET2 within a time period of the output delay time, VD2 would not output a signal for turning off the discharge control FET. After detection of an over-discharge by VD2, supply current would be reduced to typ. 0.3uA at VDD=2.0V and into standby, only the charger detector is operating. The output type of Dout pin is CMOS having “H” level of VDD and “L” level of Vss. VD3/Excess Current Detector, Short Circuit Protector Both of the excess current detector and short circuit protector can work when both control FETs are in “ON” state. When the V- pin voltage is going up to a value between the short protection voltage Vshort/VDD and excess current threshold VDET3, the excess current detector operates and further soaring of V- pin voltage higher than Vshort makes the short circuit protector enabled. This leads the external discharge control Nch MOSFET turn off with the Dout pin being at “L” level. An output delay time for the excess current detector is internally fixed, 13ms typ. At VDD=3.0V. Aquick recovery of V- pin level from a value between Vshort and VDET3 within the delay time keeps the discharge control FET staying “H” state. When the short circuit protector is enabled, the Dout would be low and its delay time would be 5us typ. The V- pin has a built-in pulled down resistor, typ. 100kOhm with connecting to the Vss pin. After an excess current or short circuit protection is detected, removing a cause of excess current or external short circuit makes an external discharge control FET to an “ON” state automatically with the V- pin level being down to the Vss level through pulled down resistor built-in internally. If VDD voltage would be higher than VDET2 at a time when the excess current is detected the T63H0002 does not enter a standby mode, or otherwise in case of lower VDD voltage than VDET2 would lead the T63H0002 into a standby. After detecting short circuit the T63H0002 will not enter a standby mode. |
