TPS3430WQDRCRQ1

The TPS3430WQDRCRQ1 is a voltage supervisor and reset IC manufactured by Texas Instruments, designed for automotive applications. This device is part of the TPS34xx family, which is known for its reliability and performance in critical automotive environments.

Key Features:

1. Voltage Monitoring: The TPS3430 monitors supply voltages and provides a reset signal when the voltage falls below a specified threshold. This is crucial for ensuring that microcontrollers and other digital devices operate correctly and do not enter an undefined state during power-up or power-down conditions.

2. Adjustable Reset Threshold: The reset threshold voltage can be adjusted, allowing designers to set the precise voltage level at which the reset signal is triggered. This flexibility is essential for accommodating various system requirements.

3. Active-Low Reset Output: The device features an active-low reset output, which means that the output signal goes low when a reset condition is detected. This output can be connected directly to the reset pins of microcontrollers or other digital logic devices.

4. Wide Operating Voltage Range: The TPS3430 operates over a wide voltage range, typically from 1.5V to 5.5V, making it suitable for a variety of automotive power supply systems.

5. Low Quiescent Current: The device is designed to consume minimal power in its idle state, which is particularly important in automotive applications where battery life and energy efficiency are critical.

6. Temperature Range: The TPS3430WQDRCRQ1 is rated for operation in extreme temperature conditions, typically from -40°C to +125°C, ensuring reliable performance in harsh automotive environments.

7. Package Type: The device is available in a small, compact package (WQFN), which is advantageous for space-constrained designs. The package is designed for easy mounting on PCBs, facilitating integration into various automotive systems.

8. Automotive Qualification: As part of the "Q1" designation, this device meets stringent automotive standards, ensuring it can withstand the rigors of automotive applications, including vibration, temperature extremes, and electrical noise.

Applications:

The TPS3430WQDRCRQ1 is suitable for a wide range of automotive applications, including:
