ZMDI, a Global Semiconductor Company, Announces the Release of the ZSPM4521, ZSPM4522, ZSPM4523 and ZSPM4551, a Family of Smart Chargers for Li-ion or NiMH Batteries or Super Caps, Utilizing Photovoltaic or Conventional Sources
DRESDEN, Germany, August 27, 2012/PRNewswire/ --
ZMD AG (ZMDI), a Dresden-based semiconductor company that specializes in enabling
energy-efficient solutions, today announces the release of the ZSPM4521, ZSPM4522,
ZSPM4523 and ZSPM4551. The ZSPM4521, ZSPM4522 and ZSPM4523 provide a
temperature-independent photovoltaic maximum power point tracking (MPPT) regulator to
optimize power output from solar sources while the ZSPM4551 is optimized for conventional
power sources. Its switching frequency of 1MHz enables the use of small filter components,
resulting in smaller board space and reduced system costs.
The integrated I2C[TM] (trademark of NXP) interface enables the user to set
application-specific temperature-compensated termination voltages with a plus or minus 1%
tolerance and control charging currents.
All four ICs can regulate up to 1.5A continuous drive current.
The ZSPM4521 and ZSPM4551 are DC/DC synchronous switching lithium-ion (Li-ion) battery
chargers with integrated power switches, internal compensation and fault protection. Both
devices contain Li-ion-specific protection for over-current, over-temperature, battery
(VBAT) over-voltage and charging timeout. In addition, they include supervisory reporting
through the NFLT (inverted fault) open-drain output to interface with other components in
the system.
The ZSPM4522 is a DC/DC synchronous switching nickel-metal hydride (NiMH) battery
charger with integrated power switches, internal compensation and fault protection
specific to NiMH batteries. It features input supply under-voltage lockout and full
protection for VBAT over-voltage.
The ZSPM4523 is a DC/DC synchronous switching super capacitor charger with integrated
power switches, internal compensation and full fault protection. It integrates a wide
range of protection circuitry, including input supply under-voltage lockout, output
over-voltage protection, current limiting and thermal shutdown.
The ZSPM452x and ZSPM4551 are in a league of their own when it comes to their high
level of integration, up to 92% efficiency with typical loads and ultra-low power
consumption. When the regulator is disabled, the devices draw less than 10microA quiescent
current.
"ZMDI [http://www.zmdi.com ] is committed to developing advanced solutions to meet our
customers' variety of needs. The ZSPM4521, ZSPM4522, ZSPM4523 and the ZSPM4551, a family
of smart chargers, support our customers' direction into portable applications, and these
products are 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.

- 1.5A continuous output current
- VBAT reverse-current blocking (VCAP for the ZSPM4523)
- Programmable temperature-compensated termination voltage
