TPS3808G33QDBVRQ1 +BOM

Top-notch voltage supervisor chip for 3.3V operation, SOT23-6 format

TPS3808G33QDBVRQ1 Information

Description

The Texas Instruments TPS3808G33QDBVRQ1 is a Power-On Reset (POR) generator with adjustable delay time, designed for automotive applications. It features a very low quiescent current consumption of 2.4 μA typical, high threshold accuracy of 0.5% typical, and available fixed threshold voltages for standard voltage rails from 1.2 V to 5 V. This chip is intended to monitor the system supply voltage and trigger a reset when it exceeds a predetermined level. It also includes manual reset (MR) input, open-drain RESET output, and operates within a temperature range of -40°C to +125°C. Designed for safety and system protection in automotive applications, it can also be used in industrial control systems and battery management systems to ensure proper voltage levels and prevent damage to circuitry. The small SOT-23 package and WSON package (only available on the TPS3808G01QDRVRQ1) make it a compact solution for space-constrained designs.

Features

The TPS3808G33QDBVRQ1 features:

  • Qualified for Automotive Applications
  • Power-On Reset Generator with adjustable delay time (1.25 ms to 10 s)
  • Very Low Quiescent Current: 2.4 μA typical
  • High Threshold Accuracy: 0.5% typical
  • Fixed threshold voltages for standard voltage rails from 1.2 V to 5 V and adjustable voltage down to 0.4 V are available
  • Manual Reset (MR) input
  • Open-Drain RESET output
  • Temperature Range: -40°C to +125°C

These features make it suitable for automotive, industrial control systems, and battery management applications where accurate voltage monitoring is required for safety and system protection.

Package

The package type of TPS3808G33QDBVRQ1 is SOT236.

Pinout

The TPS3808G33QDBVRQ1 has a pin count of 6.

Here's a concise breakdown of its pins:

  • VCC: Power supply input (3.3V)
  • GND: Ground
  • IN+: Input voltage monitor (high-side detection)
  • IN–: Input voltage monitor (low-side detection)
  • MR: Manual reset input
  • RESET: Open-drain power-on reset output

This device is a power-on reset generator with adjustable delay time, designed for automotive and industrial applications. It monitors the input voltage and generates a reset signal when the voltage falls below a certain threshold.
