FAQs
What is TPS3808G01MDBVTEP?
The TPS3808G01MDBVTEP is a voltage supervisor and reset IC manufactured by Texas Instruments. It is commonly used to monitor system voltage levels and generate a reset signal when the voltage falls below a predefined threshold. This IC is widely utilized in microcontroller-based systems, ensuring proper system initialization and operation.
How Does TPS3808G01MDBVTEP Work?
The TPS3808G01MDBVTEP works by continuously monitoring the system voltage using an internal voltage comparator. When the voltage drops below the set threshold, the IC triggers a reset pulse to the connected microcontroller, forcing it to restart and ensure reliable system operation. The device features programmable threshold levels and a manual reset input for added flexibility.
How Many Pins does TPS3808G01MDBVTEP have and What are the Functions of the Pinout Configuration?
The TPS3808G01MDBVTEP comes in a 6-pin SOT-23 package. The pinout configuration includes:
- RESET: Reset output signal.
- MR: Manual reset input for external reset control.
- GND: Ground connection.
- SENSE: External voltage sense input.
- VDD: Power supply voltage input.
- N/C: No connection pin.
