It monitors a single voltage rail at a 4.65V threshold and asserts a reset output for a minimum of 35ms after the rail rises above that threshold. The reset output is available as both Active High and Active Low signals, driven by an open-drain or open-collector stage. This gives the designer flexibility to interface with either active-low or active-high reset inputs on the downstream processor or FPGA without an external inverter. The 16-SOIC wide-body package (7.50mm width) provides adequate creepage for systems where the supervisor shares a board with higher-voltage rails. ## Active production, ROHS3 compliant No stock-holding claim is made here; availability is verified per inquiry.","metaTitle":"LTC691CSW#PBF Supervisor IC, 4.65V Threshold, 16-SOIC","metaDescription":"LTC691CSW#PBF Simple Reset/Power-On Reset IC, active high/low reset, open drain output, 35ms timeout, 4.65V threshold, 0-70°C, 16-SOIC.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Power Management (PMIC / Gate Driver)"],"specifications":{"Type":"Simple Reset/Power-On Reset","Reset":"Active High/Active Low","Output":"Open Drain or Open Collector","Package":"Tube","Mounting Type":"Surface Mount","Reset Timeout":"35ms Minimum","Package / Case":"16-SOIC (0.295\\\", 7.50mm Width)","lifecycle_stage":"eol_hot","Voltage - Threshold":"4.65V","Operating Temperature":"0°C ~ 70°C (TA)","Supplier Device Package":"16-SO","Number of Voltages Monitored":"1"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$12.24","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$12.24000","currency":"USD"},{"qty":10,"price":"$11.25200","currency":"USD"},{"qty":25,"price":"$10.78560","currency":"USD"},{"qty":100,"price":"$9.50290","currency":"USD"},{"qty":250,"price":"$9.03648","currency":"USD"},{"qty":500,"price":"$8.45350","currency":"USD"},{"qty":1000,"price":"$8.25000","currency":"USD"}]},"links":{"datasheetUrl":null,"sourceUrl":null},"ai":{"faq":[{"question":"What is LTC691CSW#PBF's reset polarity and output type?","answer":"The LTC691CSW#PBF provides both Active High and Active Low reset signals.
