说明

The MAX16140, MAX16142, MAX16144, MAX16146, MAX16156, MAX1615, MAX16158, MAX16159 are ultra-low-current, single-channel supervisory ICs that monitor the VCC voltage from 1.7V to 4.85V in approximately 50mV increments and asserts a reset when VCC voltage falls below the reset threshold. The reset output remains asserted for the reset timeout period after the VCC voltage rises above the factory-set VCC_TH + VHYS. See the Selector Guide for available reset timeout options.

The MAX16140, MAX16142, MAX16144, MAX16146, MAX16156, MAX16157, MAX16158, MAX16159 include a factory-programmable manual reset input (MR) that can be configured to assert a reset when it receives a rising-edge, falling-edge, active-low, or active-high input signal. The MAX16140/MAX16144/MAX16156/MAX16157 feature an open-drain reset output, while the MAX16142/MAX16146/MAX16158/MAX16159 feature a push-pull reset output. See the Selector Guide for reset output configurations.

All devices are specified over the -40°C to +125°C temperature range. The MAX16140/MAX16142/MAX16156/MAX16158 available in a tiny 0.73mm x 0.73mm x 0.5mm, 4-bump WLP. The MAX16144/MAX16146/MAX16157/MAX16159 are available in 5-pin SOT23 package.
