NCP1632DR2G

The NCP1632DR2G is a low-power, single-channel I2C/SMBus bus voltage supervisor with a reset output from ON Semiconductor. This device is designed to monitor the supply voltage of a system and provide a reset signal to the microcontroller or other critical components when the voltage falls below a predetermined threshold.

Description:

The NCP1632DR2G is a small, surface-mount device that comes in a 6-pin SOT-23 package. It features a programmable reset threshold, which can be set using an external resistor network. The device also includes a power-saving mode, which reduces the current consumption when the supply voltage is within the normal operating range.

Features:

• Low-power operation: The NCP1632DR2G consumes only 2.5µA in normal operation and 1µA in power-saving mode.
• I2C/SMBus interface: The device uses an I2C/SMBus interface for easy integration with other components in a system.
• Programmable reset threshold: The reset threshold can be set using an external resistor network, allowing for customization to the specific requirements of the system.
• Active-low reset output: The reset signal is active low, which means that it is asserted when the supply voltage falls below the threshold.
• Power-saving mode: The device enters a low-power state when the supply voltage is within the normal operating range, reducing power consumption.
• Small package: The SOT-23 package is compact and suitable for space-constrained applications.

Applications:

The NCP1632DR2G is commonly used in a variety of electronic systems where it is important to monitor the supply voltage and ensure that critical components are reset if the voltage falls below a safe level. Some typical applications include:

1. Microcontroller-based systems: The device can be used to monitor the supply voltage of a microcontroller and provide a reset signal if the voltage falls below a safe level.
2. Battery-powered devices: The low-power operation of the NCP1632DR2G makes it well-suited for use in battery-powered devices, where power consumption is a critical concern.
3. Industrial control systems: The device can be used to monitor the supply voltage of industrial control systems and provide a reset signal to ensure safe operation.
4. Communication systems: The NCP1632DR2G can be used to monitor the supply voltage of communication systems, such as routers and switches, and provide a reset signal to maintain reliable operation.
5. Automotive systems: The device can be used in automotive applications to monitor the supply voltage of various electronic components and provide a reset signal to ensure safe operation.

In summary, the NCP1632DR2G is a versatile, low-power voltage supervisor with a programmable reset threshold and an I2C/SMBus interface. Its small package and power-saving features make it suitable for a wide range of applications where monitoring the supply voltage and providing a reset signal is critical for safe and reliable operation.
