That means manual insertion or wave-solder assembly — not reflow. For a new high-density design, a surface-mount supervisor in SOT-23 or SC-70 would save board area and simplify assembly. But for a retrofit, a repair, or a BOM where the PCB already has a TO-92 footprint and wave-solder is the established process, this package is a direct drop-in. The formed leads match the standard TO-92 pinout: ground, reset output, and VDD from left to right when the flat face is toward you. ## Temperature grade and operating environment Rated for -40°C to 85°C ambient, the TL7757ILPR covers the industrial temperature range. That suits factory-floor controllers, outdoor telecom cabinets, HVAC systems, and instrumentation enclosures. It does not carry the extended -40°C to 125°C rating needed for under-hood automotive or downhole drilling — if that is your environment, look at the TLV803 family rated to 125°C. ## Lifecycle and compliance ROHS3 compliant, so it clears EU and other RoHS-restricted markets without exemption paperwork. The TL7757ILPR is a straightforward BOM line to maintain for the foreseeable production horizon.","metaTitle":"TL7757ILPR Simple Reset/Power-On Reset, 4.55V Threshold","metaDescription":"TL7757ILPR supervisor IC: active-low open-drain output, 4.55V threshold, 5µs max propagation delay.

An external pull-up resistor is required to produce a valid logic level."},{"question":"What is the equivalent of TL7757ILPR?","answer":"The closest functional peer in the same family is the TLV803EA29VDBZR, also a simple reset with active-low open-drain output. Key differences: the TLV803 is surface-mount (SOT-23), has a 130ms minimum reset timeout (vs 5µs propagation delay), and is rated to 125°C. It is not a direct pin-for-pin replacement due to the different package and timeout behaviour — evaluate the reset timing and footprint before substituting."},{"question":"Is TL7757ILPR a direct replacement for MAX809?","answer":"The MAX809 typically has a push-pull output, while the TL7757ILPR has an open-drain output. They are not direct drop-in replacements unless the external pull-up is accounted for and the threshold voltage matches your rail. Check the MAX809 variant threshold — the TL7757ILPR is fixed at 4.55V for 5V monitoring."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/TL7757ILPR","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/TL7757ILPR when reusing this data.
