    Rev. 1.01 / October 2014 ZSPM4523
    High-Efficiency Solar PV MPPT Regulator for Super Capacitor Systems Power Management Power and Precision ZSPM4523
    High-Efficiency Solar PV MPPT Regulator for Super Cap Systems Brief Description
    The ZSPM4523 is a DC/DC synchronous switching super capacitor charger with fully integrated power switches, internal compensation, and full fault protection. It uses a temperature-independent photovoltaic maximum power point tracking (MPPT) calculator 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 VOUT. The ZSPM4523 integrates a wide range of protection 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 IІCTM* interface through the SCL and SDA pins. Features Temperature-independent MPPT regulation VOUT reverse-current blocking Programmable temperature-compensated termination voltage: 2.48 to 2.74 V ± 1% User programmable maximum charge current: 50mA to 1500mA Input supply under-voltage lockout Full protection for VOUT over-voltage 2 I CTM program interface with EEPROM registers Charge status indication Related ZMDI Smart Power Products ZSPM4521 High-Efficiency Charger for Li-Ion Batteries with MPPT Regulator ZSPM4551 High-Efficiency Charger for Li-Ion Batteries ZSPM4121 Ultra-low Power Under-Voltage Switch ZSPM4141 Ultra-Low-Power Linear Regulator Available Support Evaluation Kit Support Documentation Physical Characteristics Benefits Up to 1.5A continuous output current High efficiency ­ up to 92% at typical load Wide input voltage range: 3.2V to 7.2V Junction operating temperature -40°C to 125°C Packaged in a 16-pin PQFN (4mm x 4mm) Photovoltaic Cells ZSPM4523 Application Circuit
