CXDR7517超低功耗电池监测仪监测单个多个锂离子电池多个碱性电池镍镉电池镍氢电池和多个铅酸电池CMOS输出消除输出颤振的滞环电源瞬态抗扰度

产品简介

The CXDR7517 is an ultra low power battery monitor,and is specially designed for monitoring single or multi lithium-ion (Li+) cells, multi-cell alkaline,NiCd, NiMH and multi-cell lead acid batteries.The device offers a single low-battery output and2Qe嘉泰姆
features fixed hysteresis. The hysteresis eliminates the output chatter sometimes associated with battery voltage monitors, usually due to input voltage noise or battery terminal voltage recovery after load removal.2Qe嘉泰姆
The device is available in 5 pin SOT23 package and is fully specified over the -40°C to +85°C extended temperature range.

Pin No.	Symbol	Description
1	GND	Negative Terminal of Power Supply(Ground)
2	VCC	Positive Terminal of Power Supply. This pin is the power supply to internal circuit.
3	LBO	Low Battery Output. CMOS output. If the voltage at LBI pin is higher than the rising threshold for more than 60ms typical, LBO will transition to high; If the voltage at LBI pin is lower than the falling threshold, LBO will transition to low.
4	LBI	Low Battery Input. The voltage that needs to be monitored is sensed at this pin. Generally LBI pin should be tied to an external resistor divider to sense the battery voltage.
5	NC	No Connection.
