Product Introduction

Overview

The TPS3836K33DBVT is a part of the TPS3836, TPS3837, and TPS3838 family of nano power voltage supervisors produced by Texas Instruments. These devices are designed to provide circuit initialization and timing supervision, primarily for digital signal processors (DSP) and processor-based systems. They operate from an input supply voltage range of 1.6 V to 6 V and are characterized for operation over a temperature range of –40°C to 85°C.The TPS3836K33DBVT specifically monitors supply voltages and asserts a reset signal when the voltage drops below a predefined threshold, ensuring proper system reset. It features a manual reset option and selectable reset delay times of 10 ms or 200 ms, depending on the connection of the CT pin.

Q & A

  1. What is the primary function of the TPS3836K33DBVT? The primary function is to provide circuit initialization and timing supervision by monitoring the supply voltage and asserting a reset signal when the voltage drops below a predefined threshold.
  2. What are the available package options for the TPS3836K33DBVT? The device is available in 5-pin SOT-23 (DBV) and 2-mm × 2-mm, 6-pin SON packages.
  3. What is the typical supply current of the TPS3836K33DBVT? The typical supply current is 220 nA.
  4. How can the reset delay time be adjusted? The reset delay time can be adjusted by connecting the CT pin to either GND (10 ms delay) or VDD (200 ms delay).
  5. What is the reset threshold voltage for the TPS3836K33DBVT? The reset threshold voltage (VIT) is typically 2.93 V.
  6. Does the TPS3836K33DBVT support manual reset? Yes, it supports manual reset.
  7. What is the operating temperature range of the TPS3836K33DBVT? The operating temperature range is –40°C to 85°C.
  8. What types of systems can the TPS3836K33DBVT be used in? It can be used in DSP and processor-based systems, automotive systems, battery-powered equipment, intelligent instruments, and wireless communication systems.
  9. What is the type of RESET output for the TPS3836K33DBVT? The RESET output is active-low, push-pull.
  10. How does the device handle power-on reset? During power-on, the RESET is asserted when the supply voltage VDD becomes higher than 1.1 V, and it remains active as long as VDD is below the threshold voltage VIT.
