19-1294; Rev 3; 1/00 3-Pin, Ultra-Low-Power SC70/SOT µP Reset Circuits General Description The MAX6326/MAX6327/MAX6328/MAX6346/MAX6347/ MAX6348 microprocessor (µP) supervisory circuits monitor the power supplies in µP and digital systems. These devices provide excellent circuit reliability and low cost by eliminating external components and adjustments when used with 2.5V, 3V, 3.3V, and 5V powered circuits. These circuits perform a single function: they assert a reset signal whenever the VCC supply voltage declines below a preset threshold, keeping it asserted for at least 100ms after VCC has risen above the reset threshold. The only difference between the devices is their output. The MAX6326/MAX6346 (push-pull) and MAX6328/ MAX6348 (open-drain) have an active-low reset output.
