Supervisor with dual-polarity reset and 145 ms timeout
The MAX16021LTET+ is a single-channel voltage supervisor from Analog Devices, providing a simple reset or power-on reset function for monitoring a 3.1 V threshold rail. It asserts a reset output — configurable as either active-high or active-low — and holds that state for a minimum of 145 ms after the monitored voltage rises above the threshold, ensuring the downstream processor or logic has stabilized before release. The push-pull, totem-pole output eliminates the need for an external pull-up resistor, simplifying the board layout for systems that require a clean, driven reset signal to a microcontroller or FPGA.
Package, footprint, and temperature grade
Housed in a 16-WQFN exposed pad package (supplier device package 16-TQFN, 4x4 mm), the part is surface-mount and intended for reflow assembly. The thermal pad should be connected to the ground plane with multiple vias to spread heat and improve reliability in high-ambient environments.
