The XC6131A161MR-G is a voltage detector manufactured by Torex Semiconductor Ltd. It's designed to monitor voltage levels and provide a reset signal when the voltage falls below a certain threshold. This is crucial for ensuring the proper operation of microcontrollers and other sensitive electronic components.

Applications

• Microcontroller reset circuits
• Power supply monitoring
• Battery-powered devices
• System voltage supervision
• Portable electronics

Features

• Accurate detection voltage (1.6V nominal in this case, as indicated by "161")
• Low supply current
• Small package (SOT-23 or similar)
• Built-in hysteresis
• Open drain output

Benefits

• Provides reliable reset functionality for microcontrollers and other devices.
• Minimizes power consumption in battery-powered applications.
• Saves board space due to its small size.
• Prevents oscillations during voltage transitions due to hysteresis.
• Offers flexibility in circuit design with an open drain output.

Additional Details

The XC6131A161MR-G requires an external pull-up resistor on its output. The datasheet contains information on the appropriate resistor value and the output voltage levels. The "MR-G" suffix indicates the package type and the lead-free status of the device. The detection voltage is a key parameter to consider when selecting this voltage detector; it should be chosen to protect the connected circuitry. Propagation delay, the time it takes for the output to respond to a voltage drop, is also an important parameter. Temperature characteristics and supply voltage range are specified in the datasheet. The device is designed to trigger a reset when the input voltage falls below the detection threshold of 1.6V.
