1 / 13 page General Description The MAX6443–MAX6452 low-current microprocessor reset circuits feature single or dual manual reset inputs with an extended setup period. Because of the extend- ed setup period, short switch closures (nuisance resets) are ignored. On all devices, the reset output asserts when any of the monitored supply voltages drops below its specified threshold. The reset output remains asserted for the reset timeout period (210ms typ) after all monitored supplies exceed their reset thresholds. The reset output is one-shot pulse asserted for the reset timeout period (140ms min) when selected manual reset input(s) are held low for an extended setup timeout period. These devices ignore manual reset transitions of less than the extended setup timeout period. The MAX6443–MAX6448 are single fixed-voltage µP supervisors. The MAX6443/MAX6444 have a single extended manual reset input. The MAX6445/MAX6446 have two extended manual reset inputs. The MAX6447/ MAX6448 have one extended and one immediate manual reset input. The MAX6449–MAX6452 have one fixed-threshold µP supervisor and one adjustable-threshold µP supervisor. The MAX6449/MAX6450 have two delayed manual reset inputs. The MAX6451/MAX6452 have one delayed and one immediate manual reset input. The MAX6443–MAX6452 have an active-low RESET with push-pull or open-drain output logic options. These devices, offered in small SOT packages, are fully guar- anteed over the extended temperature range (-40°C to +85°C).

PART TEMP RANGE PIN-PACKAGE MAX6443US_ _ _-T -40°C to +85°C 4 SOT143 MAX6444US_ _ _-T -40°C to +85°C 4 SOT143 Note: The first “_ _ ” is a placeholder for the threshold voltage level of the devices. A desired threshold level is set by the two- number suffix found in Table 1. The third "_" is a placeholder for the manual reset setup period of the devices. A desired setup period is set by the letter suffix found in Table 2. All devices are available in tape-and-reel only. There is a 2500- piece minimum order increment for standard versions (Table 2). Sample stock is typically held on standard versions only. Nonstandard versions require a minimum order increment of 10,000 pieces. Contact factory for availability. Devices are available in both leaded and lead-free packaging. Specify lead-free by replacing “-T” with “+T” when ordering. Pin Configurations continued at end of data sheet. |
