ZMDI, a Global Semiconductor Company, Announces the Release of the ZSPM4551, a Smart Charger for Lithium-Ion Batteries

DRESDEN, Germany, December 10, 2012 /PRNewswire/ --

    ZMD AG [http://www.zmdi.com ](ZMDI), a Dresden-based semiconductor company that
specializes in enabling energy-efficient solutions, today announces the release of the
ZSPM4551, a DC/DC synchronous switching lithium-ion (Li-ion) battery charger. As a global
supplier of analog and mixed-signal solutions for automotive, industrial, medical,
information technology and consumer applications, ZMDI focuses on developing families of
compact and high-efficiency products including the ZSPM4551.

    The ZSPM4551 is configurable for termination voltage, charge current and additional
variables to allow optimum charging conditions for a wide range of Li-ion batteries. Its
1MHz switching frequency enables the use of small filter components, resulting in smaller
board space and reduced system costs.

    The ZSPM4551 has an integrated I2C(TM) (trademark of NXP) interface, which enables the
user to set application-specific temperature-compensated termination voltages and control
charging currents. It can regulate up to 1.5A continuous drive current.

    The ZSPM4551 features integrated power switches, internal compensation and fault
protection. It offers Li-ion-specific protection for over-current, over-temperature,
battery (VBAT) over-voltage and charging timeout. It includes supervisory reporting
through the NFLT (inverted fault) open-drain output for interfacing with other components
in the system.

    The ZSPM4551 is in a league of its own when it comes to its high level of integration,
up to 92% efficiency with typical loads and ultra-low power consumption. When the
regulator is disabled, the device typically draws 10microA quiescent current.

    "ZMDI [http://www.zmdi.com ] is committed to developing advanced high-efficiency
solutions to meet our customers' variety of needs. Our smart charger, the ZSPM4551,
supports our customers' direction into portable applications, and this product is another
example of ZMDI's commitment to providing the very best solutions for our energy-conscious
customers," stated Edward Lam, Vice President of Product Marketing and Business
Development at ZMDI.

    Smart Charger Features:

       
        - 1.5A continuous output current
        - VBAT reverse-current blocking
        - Programmable temperature-compensated termination voltage
        - User-programmable charging current
        - VBAT over-voltage and charging-timeout supervisor for VBAT reported at the
          NFLT pin
        - Input supply under-voltage lockout
        - Full protection for over-current and over-temperature
