Product details

What the 4.55V threshold means for your 5V rail

That threshold is set for 5V nominal systems — it triggers before the logic rails brown out, giving the processor or FPGA time to execute an orderly shutdown. The active-low, open-drain output lets you wire-OR it with other reset sources on the same net. With a maximum propagation delay of 5µs, the reset asserts fast enough to catch even short glitches on the supply line.

Package and mounting — through-hole for prototyping and legacy boards

Housed in a TO-92-3 (TO-226AA) through-hole package, this part is a direct fit for breadboards, prototype boards, and existing designs that use through-hole supervisors. The three-pin layout — ground, reset output, and sense input — is standard for this function class, making it a drop-in replacement for many TO-92 voltage monitors.

Lifecycle and supply posture

For BOM planning, this is a stable line — no urgency to qualify an alternate unless you need surface-mount or a wider temperature range.

Frequently asked questions

What is an equivalent or replacement for TL7757ILP?

A functional equivalent is the TLV803EA29VDBZR, which is also an active-low, open-drain simple reset supervisor. However, the TLV803EA29VDBZR has a 130ms minimum reset timeout, a different threshold (2.93V), and is surface-mount (SOT-23-5), so it is not a pin-compatible drop-in. The TL7757ILP remains the direct choice for through-hole 5V monitoring.
