In Energy Harvesting power management circuits which convert small energy obtained from the surrounding environment into electric power, it’s necessary to minimize the current consumption. Likewise, quiescent current suppression is very important in cell monitoring circuits and electric storage devices, such as small lithium ion batteries or LIC/EDLC’s used in wearable devices that require long battery life.

Ultra Low Power Voltage Detectors

The AP4400 / AP4410 products family is a voltage detection IC with a world-class low power characteristic.

Ultra-Low Power Consumption Voltage Detection IC with MOSFET
AP4410BEC

● Ultra-low Power Consumption

The AP4410BEC has low operation current of 26nA (Typ.) Therefore, voltage detection circuits with low current consumption can be designed with the AP4410BEC.

● Support Wide Hysteresis

Both over-discharge and overcharge protections can be designed since the AP4410BEC has wide detection voltage range.

● Ultra-small Package

The AP4410BEC is housed in a 20-pin WLCSP (1.955×1.555mm), ideal for space saving small printed circuit boards.
