Drawing only 22 microamps of standby current, the NCV8664 provides increased design flexibility to meet tight quiescent current targets

CONVERGENCE – DETROIT, Mich. – October 16, 2006 - ON Semiconductor (Nasdaq: ONNN), a global leader in power management products, today introduced the NCV8664 – the industry’s first linear regulator to incorporate reverse battery, short circuit and overload protection with the lowest quiescent (Iq) current performance specified over a wide automotive temperature range.

An increased number of on-board automotive system power modules need to meet stringent requirements for ignition-off current. Many of these modules have specified currents of less than 100 microamps (μA) of current. Power optimization in the new NCV8664 enables designers to minimize the quiescent current for the regulation portion of the module, allowing higher system level design for controller-area networks (CAN or LIN), microprocessors, and other system overhead.

The NCV8664 is a low drop out (LDO) regulator with a precision 5 volt (V) fixed output and an output current capability of 150 milliamps (mA). Optimized for use in automotive electronics modules requiring tight quiescent currents, the NCV8664 draws only 22 μA typical and 30 μA maximum of quiescent current specified from -40C to 85C. This is a wider temperature range than most low Iq regulators on the market. The output voltage of the LDO is accurate to within ±2.0 percent. The device is also internally protected against input supply reversal, output overcurrent faults, and excess die temperature.

“As electronics have become more pervasive in automobiles, lowering the quiescent current of each power module to minimize overall battery drain has become increasingly important,” said Andy Williams, ON Semiconductor senior vice president and general manager of the Automotive and Power Regulation Division. “ON Semiconductor is committed to developing and delivering versatile, high performance solutions, such as the NCV8664, to help designers meet these ongoing power system challenges. During the next few quarters, ON Semiconductor plans to further expand its portfolio of low quiescent current regulators to provide additional family members.”
