1 / 12 page MAX6412–MAX6420 Low-Power, Single/Dual-Voltage µP Reset Circuits with Capacitor-Adjustable Reset Timeout Delay For pricing, delivery, and ordering information, please contact Maxim Direct at 1-888-629-4642, or visit Maxim’s website at www.maximintegrated.com. General Description The MAX6412–MAX6420 low-power microprocessor supervisor circuits monitor system voltages from 1.6V to 5V. These devices are designed to assert a reset signal whenever the VCC supply voltage or RESET IN falls below its reset threshold or the manual reset input is asserted. The reset output remains asserted for the reset timeout period after VCC and RESET IN rise above the reset threshold and the manual reset input is deasserted. The reset timeout is externally set by a capacitor to provide more flexibility. The MAX6412/MAX6413/MAX6414 feature fixed thresholds from 1.575V to 5V in approximately 100mV increments and a manual reset input. The MAX6415/MAX6416/MAX6417 are offered with an adjustable reset input that can monitor voltages down to 1.26V and the MAX6418/MAX6419/ MAX6420 are offered with one fixed input and one adjustable input to monitor dual-voltage systems. The MAX6412/MAX6415/MAX6418 have an active-low, push-pull reset output. The MAX6413/MAX6416/ MAX6419 have an active-high, push-pull reset output and the MAX6414/MAX6417/MAX6420 have an active- low, open-drain reset output. All of these devices are offered in a SOT23-5 package and are fully specified from -40°C to +125°C.

Insert the desired nominal reset threshold suffix (from Table 1) into the blanks following the letters UK. There are 33 standard versions with a required order increment of 2500 pieces. Sample stock is generally held on standard versions only (see Standard Versions Table). Required order increment is 10,000 pieces for nonstandard versions. Contact factory for availability. All devices are available in tape-and-reel only. Devices are available in both leaded and lead-free packaging. Specify lead-free by replacing “-T” with “+T” when ordering. /V denotes an automotive qualified part. |
