Description

TPS3897PDRYR is Texas Instruments’ voltage supervisor (reset IC) in the TPS3897 family. It monitors VDD and asserts a clean reset to a microcontroller or other digital logic when the supply is out of range or during power-up, providing deterministic POR/brown-out protection without external components.
Key points:
- Fixed-threshold options (select variant) around typical ranges like 2.3–3.3 V.
- Very low quiescent current for battery-powered designs.
- Reset output (usually active-low) with fast, reliable release on power-up.
- Small package; PDRYR suffix indicates a specific package/reel option—check the TI datasheet for exact packaging details.
Common uses: MCU reset and brown-out protection, power-on reset in embedded systems. For exact thresholds, packages, and electrical specs, refer to the TI TPS3897PDRYR datasheet.

Features

TPS3897PDRYR is a TI voltage supervisor/reset generator. Key features:
- Ultra-low quiescent current (typical microamps)
- Wide operating supply range (roughly 1.8 V to 5.5 V)
- Power-on reset/power-down reset with a defined reset output
- Active-low, push-pull reset output
- Manual reset input to force a reset when needed
- Glitch-tolerant/reset-filtering to avoid spurious resets
- Temperature range suitable for industrial applications (-40°C to 125°C)
- Small 5-pin SOT-23 package (PDRYR indicates Tape & Reel, RoHS compliant)
- Suitable for MCU/processor reset supervision and battery-powered devices
Note: exact voltage thresholds and timing are variant-specific; refer to the datasheet for the precise values for this PDRYR variant.

Package

TPS3897PDRYR comes in an 8-pin VSSOP package (Very Small Outline No-lead), Tape & Reel.

Pinout

- Pin count: 6 pins (SC70/SOT-23-6 package variant).
- Function: TI TPS3897PDRYR is a voltage supervisor/reset IC. It monitors the supply voltage and provides a reset output to a microcontroller (with an optional manual reset input to trigger a reset).

Manufacturer

- Manufacturer: Texas Instruments Incorporated (TI).
- What kind of company: A multinational American semiconductor company that designs and manufactures analog, mixed-signal, and embedded processing integrated circuits.

Application

TPS3897PDRYR is a voltage supervisor/reset IC. Typical applications include:
- Generating proper MCU/reset signals on power-up/power-down
- Monitoring supply rails in embedded/IoT and battery-powered devices
- Supervising DC-DC converters and PMIC rails
- Ensuring reliable operation of digital electronics in consumer and industrial systems
