The MAX16060/MAX16061/MAX16062 are 1% accurate, quad-/hex-/octal-voltage µP supervisors in a small thin QFN package. These devices provide supervisory functions for complex multivoltage systems. The MAX16060 monitors four voltages, the MAX16061 monitors six voltages, and the MAX16062 monitors eight voltages. These devices offer independent outputs for each monitored voltage along with a reset output that asserts whenever any of the monitored voltages fall below their respective thresholds (down to 0.4V) or the manual reset input is asserted. The reset output remains asserted for the reset timeout after all voltages are above their respective thresholds and the manual reset input is deasserted. The minimum reset timeout is internally set to 140ms or can be adjusted with an external capacitor. All open-drain outputs have internal 30µA pullups that eliminate the need for external pullup resistors. However, each output can be driven with an external voltage up to 5.5V. Other features offered include a manual reset input, a tolerance pin for selecting 5% or 10% input thresholds, and a margin enable function for deasserting the outputs during margin testing. An additional feature is a watchdog timer that asserts RESET when the watchdog timeout period (1.6s typ) is exceeded. The watchdog timer can be disabled by leaving WDI unconnected. These devices are offered in 16-, 20-, and 24-pin thin QFN packages (4mm x 4mm) and are fully specified from -40°C to +1°C.
The MAX16060, MAX16061 and MAX16062 are µP supervisors that monitor four, six or eight voltages respectively. Each monitored voltage has an independent open‑drain output and a common reset output that asserts when any voltage falls below its threshold or when the manual reset input is activated. The devices include a tolerance pin, margin enable, and a watchdog timer.
All devices are offered in thin QFN packages (16‑, 20‑ or 24‑pin, 4 mm × 4 mm) and operate from –40 °C to +125 °C. Open‑drain outputs feature internal 30 µA pull‑up resistors, eliminating the need for external pull‑ups. The reset timeout is programmable, with a minimum of 140 ms, and the watchdog timer provides a typical 1.6 s timeout.
