Key Features
- Fixed 1.7V threshold voltage with active-low push-pull reset output, eliminating the need for external pull-up resistors and simplifying PCB layout
- Manual reset input (MNL RST) enabling system reset via external button or controller signal without additional discrete components
- Tiny 3-pin SOT-23 (TO-236) package consuming less than 2 mm² of PCB area, ideal for space-constrained mobile and wearable designs
Applications
TLV809EA17DBZR is used to supervise power rails in low-voltage microcontroller systems, ensuring the MCU is held in reset until the supply reaches 1.7V and remains stable. Battery-powered IoT nodes, wearables, and portable medical devices benefit from its ultrasmall SOT-23 footprint and minimal quiescent current, which preserves battery charge. Embedded systems with manual reset buttons also benefit from its integrated MNL RST pin, reducing external component count to a single device.

Frequently Asked Questions
Why is TLV809EA17DBZR's 1.7V threshold well-matched to MCUs running from a 1.8V supply rail?
Many modern 32-bit microcontrollers operate from a 1.8V nominal supply and require a valid reset signal until the rail rises above their minimum operating voltage, typically 1.62V. TLV809EA17DBZR's 1.7V threshold asserts reset (pulls RESET low) whenever VCC falls below 1.7V, providing approximately 100mV of headroom above the MCU's minimum before releasing reset. This prevents erratic code execution during supply ramp-up or brownout events, which could cause data corruption or peripheral misconfiguration in embedded systems.
How does TLV809EA17DBZR's push-pull active-low output differ from an open-drain reset output in a multi-supervisor system?
TLV809EA17DBZR's push-pull output actively drives RESET both low (during fault) and high (during normal operation) without requiring an external pull-up resistor, reducing component count by 1 resistor per supervisor. An open-drain output can share the reset line among multiple supervisors through wire-OR connection, but requires a pull-up resistor and the combined leakage current of all devices on the node. For single-supervisor designs, TLV809EA17DBZR's push-pull eliminates the pull-up, saving board area and ensuring faster reset release with lower output impedance at 3-pin SOT-23 scale.
For a wearable device design, how does TLV809EA17DBZR's SOT-23 package size and quiescent current impact overall system power budget?
TLV809EA17DBZR occupies a 3-pin SOT-23 (TO-236) footprint with a body of approximately 1.3 mm × 2.9 mm, consuming under 4 mm² including recommended pad clearances. Voltage supervisors in this class typically draw 5 µA to 15 µA quiescent current, which adds under 0.1 mAh per day to the power budget of a coin-cell wearable running from a CR2032 (220 mAh). This negligible power draw allows TLV809EA17DBZR to monitor the 1.7V power rail continuously without measurably shortening battery runtime.
