Brief Description
The ZSPM4551 is a DC/DC synchronous switching
lithium-ion (Li-Ion) battery charger with fully inte-
grated power switches, internal compensation, and
full fault protection.
Its switching frequency of 1MHz enables the use of
small filter components, resulting in smaller board
space and reduced BOM costs.
In Full-Charge Constant-Current Mode, the regula-
tion is for constant current (CC). Once termination
voltage is reached, the regulator operates in voltage
mode. When the regulator is disabled (the EN pin is
low), the device draws 10µA (typical) quiescent
current.
The ZSPM4551 includes supervisory reporting
through the NFLT (inverted fault) open-drain output
to interface other components in the system. Device
programming is achieved by an I²C™* interface
through the SCL and SDA pins.
