GENERAL DESCRIPTION
The ACT4921 device is a highly integrated power loss
protection IC. It provides backup storage power in the
event of an input power failure. A built-in boost
converter provides high voltage energy storage to
minimize storage capacitor size requirements. The
built-in buck converter regulates the storage voltage to
a fixed output voltage. It contains internal, back-to-
back eFuse FETs to provide bi-directional input to
output isolation. The IC also provides hot swap and
inrush current control.
The ACT4921 is very flexible and can easily be
configured with I2C and external components. It
features programmable storage capacitor voltage to
optimize the storage capacitor sizing and system run
time. The internal health monitoring provide an extra
layer of protection and improve system reliability and
early capacitor failure notification. It automatically
checks the storage capacitor health and notifies the
user when the energy in the storage caps is not
sufficient for backup power. The built-in synchronous
buck converter maximizes energy transfer from the
storage caps to the system.
ACT4921 provides an I2C bus interface to allow MCU
control and monitoring. There are supervisor monitors
for the input voltage, output voltage, and storage
voltage. It is available with the thermal enhanced QFN
4x4 32 pin package.
