Ultra-Low Power Consumption Voltage Detection IC with MOSFET


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.


Asahi Kasei Microdevices Corporation, (AKM), has developed a highly accurate CMOS voltage detection IC, the AP4410BEC in response to this demand. It integrates a voltage detection circuit and P-FET to control an external device and 2 N-FET channels, (individual channels controlled via logic), while featuring the world class ultra-low power consumption of 26 nA (Typ.) Samples of the AP4410BECSJ and AP4410EBCJT are available now.

  • Ultra-low Power Consumption
    The AP4410BEC has low operation current of 26 nA (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 × 1.555 mm), ideal for space saving small printed circuit boards.
