CXDR7517是一款超低功耗电池监视器，专门用于监测单或多锂离子电池、多电池碱性电池、镍镉电池、镍氢电池和多电池铅酸电池。该设备提供单电池低输出和具有固定滞后。磁滞消除了有时与蓄电池电压监测器相关的输出抖动，通常是由于输入电压噪声或负载消除后蓄电池端子电压恢复引起的。

产品概述 返回TOP
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 and
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.
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. |
