Brief Description

The ZSPM4523 is a DC/DC synchronous switching

super capacitor charger with fully integrated power

switches, internal compensation, and full fault pro-

tection. It uses a temperature-independent photo-

voltaic maximum power point tracking (MPPT) calcu-

lator to optimize power output from the source during

Full-Charge Mode. Its 1MHz switching frequency

allows using small filter components, which results in

smaller board space and reduced bill-of-material

costs.

In Full-Charge Mode, the duty cycle is controlled by

the MPPT function. Once the termination voltage is

reached, the regulator operates in Constant Voltage

Mode. When the regulator is disabled (the EN pin is

low), the device draws 10µA (typical) quiescent

current from V

The ZSPM4523 integrates a wide range of protec-

tion circuitry, including input supply under-voltage

lockout, output over-voltage protection, current

limiting, and thermal shutdown.

The ZSPM4523 includes supervisory reporting via

the NFLT (Inverted Fault) open-drain output to

interface other components in the system. Device

programming is achieved by the I²C™* interface

through the SCL and SDA pins.
