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.
