DALLAS--(BUSINESS WIRE)--Mar. 17, 2009--
Diodes Incorporated (NASDAQ:DIOD), a leading global manufacturer and
supplier of application specific standard products within the broad
discrete and analog semiconductor markets, today announced an active
OR’ing controller chip, enabling shared power system designers to
replace heat-dissipating blocking diodes with high efficiency MOSFETs.
The ZXGD3102 ensures cool running, low maintenance and high reliability
operation in up-time critical telecom, server and mainframe applications.
The high heat dissipated by Schottky blocking diodes, traditionally used
to protect a load from faulty power supplies, relates directly to the
hefty 0.5V forward voltage drop. Replacing the diodes with low
on-resistance MOSFETs, which have typical forward voltages of under
100mV, means that power dissipation is greatly reduced. The ZXGD3102 is
specifically designed to control MOSFETs in high-reliability N+1
redundant power systems.
Sinking a peak turn-off current of 5A, the controller’s gate drive is
able to achieve a typical MOSFET turn-off time of 160ns, ensuring the
rapid load protection that is needed to avoid any variation in bus
voltage in the event of a power supply failure and hot-swapping. To meet
the fault handling requirements, turn-on time can be adjusted to enable
a smooth handover between supplies. The ZXGD3102’s input voltage
blocking capability is 180V.
The ZXGD3102 is housed in the compact SM8 package and requires a minimal
external component count. The ZXGD3102 uses a 5 to 15V low-current bias
rail, which is easily derived using a miniature zener diode.
