Maxim MAX14654EWC+T

Защита аккумулятораЛитий-ионный-40°C ~ 85°C (TA)

Overview

The MAX14653/MAX14654/MAX14655/MAX14717 overvoltage protection devices feature a low 38mΩ (typ) RON internal FET and protect low-voltage systems against voltage faults up to +28VDC. An internal clamp also protects the devices from surges up to +80V. When the input voltage exceeds the overvoltage threshold, the internal FET is turned off to prevent damage to the protected downstream components. The overvoltage protection threshold can be adjusted with optional external resistors to any voltage between 4V and 20V. With the OVLO input set below the external OVLO select voltage, the MAX14653/MAX14654/MAX14655/MAX14717 automatically choose the accurate internal trip thresholds. The internal overvoltage thresholds (OVLO) are preset to 15.5V typical (MAX14653), 6.8V typical (MAX14654/MAX14717), or 5.825V typical (MAX14655). The devices feature an open-drain active-low ACOK output indicating a stable supply between minimum supply voltage and VOVLO. The MAX14653/MAX14654/MAX14655/MAX14717 are also protected against overcurrent events by an internal thermal shutdown. The MAX14653/MAX14654/MAX14655/MAX14717 are offered in a small 12-bump WLP package and operate over the -40°C to +85°C extended temperature range.
