Frequently Asked Questions
What supply voltage range can TPS3897ADRYR monitor and how is the threshold set?
TPS3897ADRYR monitors supply voltages from 1 V to 5.5 V. The reset threshold is set externally using a resistor divider connected to the adjustable threshold pin, giving designers precise control over the trip point without needing a different device for each rail voltage.
Which applications benefit most from the ultra-compact 1.2 mm x 1.0 mm WSON-6 package of TPS3897ADRYR?
The 1.2 mm x 1.0 mm, 6-pin WSON package is ideal for space-constrained designs such as wearables, IoT sensor nodes, and compact industrial modules where a traditional SOT-23 supervisor would consume too much board area, saving up to 50% PCB space compared to larger packages.
Over what temperature range does TPS3897ADRYR operate, and does it meet automotive-grade requirements?
TPS3897ADRYR operates over a -40°C to 125°C temperature range, meeting the thermal requirements of automotive and industrial applications. The device is AEC-Q100 qualified at Grade 1, making it suitable for under-hood automotive supervisory circuits alongside engine control units and ADAS modules.
How does the active-high open-drain output of TPS3897ADRYR simplify system reset circuit design?
The active-high, open-drain output allows multiple supervisors or logic signals to be wire-OR connected on a single reset line using a single external pull-up resistor of typically 100 kΩ, simplifying multi-supply reset architectures and reducing component count by eliminating inverters or additional logic gates.
