Overview
The TPS3435 is a precision voltage supervisor with nano-quiescent current, designed for monitoring single or multiple supply rails. It features an adjustable reset threshold, manual reset input, and watchdog timer functionality. The device operates from 1.04 V to 6 V with ultra-low power consumption of 250 nA. Available in compact SOT-23-THIN-8 packages, it supports active low, open drain, or push-pull outputs. Ideal for battery-powered and space-constrained applications requiring reliable system supervision.
Feature Summary
- Ultra-low quiescent current for extended battery life
- Adjustable reset threshold voltage for flexible design
- Integrated watchdog timer with timeout function
- Manual reset input for system control
Applications
- Portable electronic devices
- Battery-powered systems
- Industrial control units
- Embedded microcontroller supervision
Procurement Notes
Verify the exact suffix (e.g., CAKAGDDFR) against official Texas Instruments documentation to confirm package type, temperature range, and output configuration. Ensure compatibility with your system's voltage levels and reset requirements before procurement.
Selection Notes
Select based on required reset threshold voltage, output drive type (open drain vs. push-pull), and package constraints. Confirm operating temperature range matches application environment. Verify if manual reset and watchdog features are necessary for system reliability.
Part Context
The TPS3435 belongs to Texas Instruments' family of precision voltage supervisors. These components are critical for ensuring system stability by monitoring power rails and initiating resets when voltages fall outside specified limits. They complement other PMICs in complex power management architectures.
Replacement Considerations
Check for direct pin-compatible alternatives within the TPS343x series or similar supervisors from other manufacturers. Verify that replacement parts meet the same electrical specifications, particularly quiescent current, reset accuracy, and operating voltage range.
