What are the key features of HPA00763DCKR?
- Adjustable reset threshold allows a single IC to monitor custom supply voltages without fixed-threshold part proliferation
- Ultra-compact SOT-23-5 (5-pin) package with active-low reset output minimizes PCB area in space-constrained embedded designs
- RoHS-compliant (JESD-609 e4) plastic/epoxy construction meets lead-free requirements for consumer and industrial applications
What is HPA00763DCKR used for?
HPA00763DCKR is used to assert a processor reset signal whenever a monitored supply rail drops below the programmed threshold voltage, preventing microcontrollers from executing corrupted instructions during power-up or brown-out events. It suits single-board computers, industrial PLCs, and consumer electronics where reliable reset behavior is essential for system integrity. Its adjustable threshold and minimal external component requirement make it an efficient solution for 3.3 V, 5 V, and custom supply-rail monitoring.

Frequently Asked Questions
How does HPA00763DCKR's adjustable threshold differ from fixed-threshold voltage supervisors?
HPA00763DCKR provides an adjustable reset threshold through external resistor dividers, allowing engineers to set the undervoltage trip point for any supply rail rather than selecting from a fixed set of standard voltages. Fixed-threshold supervisors force the designer to choose a part matching the exact supply — for example, a 3.0 V or 3.3 V version — while the adjustable threshold covers a continuous range with 1 component. This reduces SKU count and inventory cost in multi-rail system designs.
What reset output polarity and timing characteristics does HPA00763DCKR provide for processor integration?
HPA00763DCKR asserts an active-low reset output (RESET#) that holds the processor in reset while the monitored supply is below the programmed threshold. The reset remains asserted for a minimum reset timeout period after the supply recovers — typically tens of milliseconds — giving the processor time to stabilize before execution begins. This prevents false start issues on cold-boot cycles where capacitor charging can cause slow supply ramp-up.
For a 5-pin SOT-23 design, how many external components does HPA00763DCKR require for basic reset operation?
HPA00763DCKR in its SOT-23-5 package typically requires only 2 external resistors to set the adjustable threshold voltage, plus optional bypass capacitors — making the total solution as few as 3–4 passive components. The 5 pins carry VCC, GND, RESET# output, and the sense input, keeping the schematic minimal. This low component count suits designs constrained by BOM size or board space, such as IoT sensor nodes and portable instruments.
Is HPA00763DCKR a direct replacement for TPS3801-01DCKR in existing layouts?
Yes, HPA00763DCKR is the house-numbered equivalent of TPS3801-01DCKR and shares the same SOT-23-5 (JESD-30 R-PDSO-G5) package footprint and 0.8 mm pitch. Designers can substitute HPA00763DCKR in existing TPS3801-01DCKR PCB layouts with no mechanical changes. Both carry the JESD-609 e4 RoHS-compliant designation, so the substitution does not affect regulatory compliance for CE or RoHS-marked products.
