The application field of TLV809J25DBZT encompasses a wide range of applications including automotive, consumer electronics, communications, computing, industrial, and medical. It can be used in a variety of applications such as automotive electronics, consumer electronic device power monitoring and reset, industrial control, consumer electronic system reset and power management, industrial control system, low power consumer devices, and consumer medical systems. It can also be used for voltage and temperature monitoring, voltage monitoring and system reset, and high-current over-current shutdown protection in consumer products, as well as consumer motor control.

TLV809J25DBZT Working Principle

The wide operating range of the TLV809J25DBZT from -40C to 125°C and high-current protection with a wide VIN range allows for use in various applications. The device provides solutions for power monitoring, system reset, and precision voltage monitoring for a wide range of applications. The device is designed to monitor a number of power rails, provide power sequencing and reset, and protect against over-voltage, under-voltage, over-temperature, and over-current conditions.

The TLV809J25DBZT features a pull-down resistor and semiconductor-based reset circuit to protect consumer systems from just such conditions. The input voltage range of the reset circuit encompasses the system’s normal operating range, ensuring that the device functions correctly. In the event of an over-voltage or over-temperature condition, the pull-down resistor activates the reset line and powers down the consumer system to prevent costly damage and disruption.

The TLV809J25DBZT also features a temperature sensor circuit, capable of monitoring system temperature and providing accurate low temperature protection. The on-chip temperature sensor monitors up to four temperature zones, enabling the user to monitor, protect, and control the temperature in their application. The device can also be used with an external sensor to extend the temperature range, providing flexibility to address various temperature requirements.

TLV809J25DBZT also includes an on-chip precision voltage monitoring circuit, which can be used to accurately monitor system voltage in order to detect faults and prevent costly damage. The voltage monitoring circuit continuously samples the input voltage and compares it against a limit voltage set by the user, ensuring that the system operates within the desired operating range. If the voltage rises above the predefined value, the voltage monitoring circuit triggers a power-down to protect the system.

TLV809J25DBZT is an innovative power monitoring integrated circuit with a wide range of applications in the consumer, automotive and corporate markets. With features such as reset-line protection, temperature monitoring, and precision voltage monitoring, the TLV809J25DBZT provides comprehensive power monitoring and protection solutions for applications from consumer electronics and motors to industrial controls and computing systems.
