Consuming just 125 nA, the MAX16056 - MAX16059 is a quartet of microprocessor supervisory circuits that monitor a single system-supply voltage. Thanks to their extremely low current consumption, these devices help extend battery life in power-sensitive applications. Additionally, the devices feature capacitor-adjustable watchdog (MAX16056/MAX16058) and reset timeouts to maximize design flexibility. This configurability makes it easy for designers to quickly change design parameters, and enables the supervisors to be used in unique power-saving schemes. The MAX16056-MAX16059 can monitor voltages from 1.575 V to 4.625 V. These devices assert a reset signal whenever the Vcc supply voltage drops below the reset threshold, manual reset is pulled low, or the watchdog timer (MAX16056/MAX16058) runs out. The reset function features immunity to power-supply transients. The MAX16056-MAX16059 operate from voltages from 1.1 V to 5.5 V and are available in either push-pull or open-drain output configurations. A manual-reset input facilitates testing. All devices are fully specified over the -40°C to +125°C automotive temperature range. The MAX16056/MAX16058 are available in a 3-mm x 3-mm, 8-pin TDFN package, and the MAX16057/MAX16059 are available in a 3-mm x 3-mm, 6-pin TDFN package. Prices start at $1.10 each in lots of 1000. Samples are now available. MAXIM INTEGRATED PRODUCTS, Sunnyvale, CA. (800) 998-8800.
