In modern electronic system design, stable monitoring of power supply voltage and reliable system reset are the cornerstones of ensuring proper device operation. Mingjiada Electronics is pleased to recommend the TPV706SL1-SR power monitoring and reset chip from 3PEAK to our customers. With its precise low-voltage monitoring, integrated watchdog timer, and ultra-low power consumption, this product is specifically designed for applications such as microprocessor systems, industrial controllers, and smart meters.
Product Overview: Highly Integrated Monitoring Solution
The TPV706SL1-SR is a feature-rich system monitoring circuit designed to provide a power-on reset signal for digital systems by monitoring the power supply voltage. Manufactured by 3PEAK, a leading domestic analog chip manufacturer, this chip is housed in an SOP-8 package suitable for surface-mount technology, meeting the requirements of compact PCB designs.
Key Features and Technical Advantages
This chip integrates multiple key functions to provide comprehensive protection for stable system operation:
1. Precise Low-Voltage Monitoring and Reset Output
The TPV706SL1-SR features a built-in precision voltage detector with a threshold voltage of 2.93V, capable of accurately monitoring a single power supply voltage. When the detected voltage falls below the threshold, the chip outputs an active-low reset signal, ensuring the microprocessor remains in a reset state during periods of voltage instability. Its push-pull output structure eliminates the need for external pull-up resistors, simplifying circuit design.
2. Integrated Watchdog Timer
To prevent system programs from running out of control or entering a deadlock, the TPV706SL1-SR integrates an independent watchdog timer. If the watchdog input (WDI) does not trigger a state change within 1.6 seconds, the chip will trigger a reset signal. This feature is critical for industrial controllers and computer systems that require high reliability.
3. Manual Reset and Power-Down Detection
In addition to automatic monitoring functions, the chip supports an external manual reset input (MR), allowing users or external logic to force a system reset. Furthermore, it includes an internal power-down detector with a 1.25V threshold, which can be used to monitor auxiliary power supplies or implement low-voltage warning functions.
4. Ultra-Low Power Consumption and Wide Operating Temperature Range
The TPV706SL1-SR has a typical quiescent current of only 4 μA, making it ideal for battery-powered portable devices. At the same time, its operating temperature range spans from -40°C to 125°C, enabling it to withstand harsh industrial environments.
Key Application Areas
The TPV706SL1-SR is widely applicable in the following scenarios:
Microprocessor/Microcontroller (MCU) Systems: Provides a reliable reset signal for power-up sequencing and voltage sags.
Industrial Controllers and PLCs: The built-in watchdog prevents system freezes, ensuring continuous and stable production processes.
Computers and Peripherals: Ensures that motherboards and critical circuit boards are safely locked during power fluctuations.
Smart Instruments and Portable Devices: Low-power characteristics extend battery life, while the compact package saves PCB space.
