Low-Power, Small, High-Voltage Detection/Protection Circuits Operate Up to 72V

Note to Editor: The MAX16010-MAX16014 are overvoltage protection/detection circuits that operate from 5.5V to 72V. These circuits are ideal for high-voltage applications as found in automotive, industrial, server, and battery stack applications. The devices have different integrated functions, all providing a range of overvoltage/undervoltage protection and/or monitoring. All devices are offered in a small, 3mm x 3mm TDFN, and are fully specified from -40 degrees Celsius to +125 degrees Celsius.

SUNNYVALE, CA-January 27, 2006-Maxim Integrated Products (NASDAQ: MXIM) introduces the MAX16010-MAX16014 overvoltage protection circuits designed for systems with high transient voltages as found in automotive, industrial, and telecommunication applications. These devices operate from 5.5V to 72V, and can be configured to provide overvoltage, undervoltage, or window monitoring while consuming only 20 microamps of quiescent current.

The MAX16010 and MAX16011 have two independent comparators for monitoring both overvoltage and undervoltage conditions. The MAX16010 provides complementary enable inputs, while the MAX16011 offers an active-high enable input and a logic input to invert one of the two outputs.

Offering greater design flexibility, the MAX16012 has a comparator providing access to both inverting and noninverting inputs, along with a reference output. The device can be configured to monitor either overvoltage or undervoltage conditions.

The MAX16013 and MAX16014 are overvoltage protection circuits capable of driving two external p-channel MOSFETs to prevent reverse battery and overvoltage conditions. The MAX16014 also features a latch-off feature to keep the load disconnected until the power is recycled.

All devices are offered in a small, 3mm x 3mm TDFN package and are fully specified from -40 degrees Celsius to +125 degrees Celsius. Prices for these devices start at $1.08 (1000-up, FOB USA).
