It monitors a single voltage rail and asserts a reset signal — either active-high or active-low — when the supply drops below the programmed threshold. The output is open-drain, so you choose the pull-up voltage and logic family. The reset timeout is a minimum of 250 ms, long enough for most MCUs and SoCs to complete their initialization sequence before the supervisor releases the reset line. ## Threshold selection and supply compatibility Two factory-set voltage thresholds are available: 4.37 V and 4.62 V. These are the trip points at which the reset asserts when the monitored rail falls below the selected value. ## Lifecycle and sourcing The MAX1232ESA+T is listed as Active with ROHS3 compliance. There is no end-of-life notice or last-time-buy schedule.","metaTitle":"MAX1232ESA+T Simple Reset/Power-On Reset, 250ms Timeout","metaDescription":"MAX1232ESA+T is an active Simple Reset/Power-On Reset supervisor with 250ms minimum timeout, open-drain output, and 4.37V/4.62V thresholds.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Analog & Data Acquisition"],"specifications":{"Type":"Simple Reset/Power-On Reset","Reset":"Active High/Active Low","Output":"Open Drain or Open Collector","Package":"Tape & Reel (TR); Cut Tape (CT)","Mounting Type":"Surface Mount","Reset Timeout":"250ms Minimum","Package / Case":"8-SOIC (0.154\\\", 3.90mm Width)","lifecycle_stage":"eol_hot","Voltage - Threshold":"4.37V, 4.62V","Operating Temperature":"-40°C ~ 85°C (TA)","Supplier Device Package":"8-SOIC","Number of Voltages Monitored":"1"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$4.39","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$4.39000","currency":"USD"},{"qty":10,"price":"$3.94200","currency":"USD"},{"qty":25,"price":"$3.72680","currency":"USD"},{"qty":100,"price":"$3.23000","currency":"USD"},{"qty":250,"price":"$3.06432","currency":"USD"},{"qty":500,"price":"$2.74962","currency":"USD"},{"qty":1000,"price":"$2.31896","currency":"USD"},{"qty":2500,"price":"$2.20301","currency":"USD"}]},"links":{"datasheetUrl":"https://datasheets.maximintegrated.com/en/ds/MAX1232.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Does MAX1232ESA+T work with 5V and 3.3V supplies?","answer":"The MAX1232ESA+T monitors a single voltage rail with thresholds of 4.37 V and 4.62 V, which are intended for 5 V nominal supplies.
