PMIC - Supervisors

PMIC (Power Management ICs) are integrated circuits used to regulate the power supply within a device, by providing a reliable power source to the required components. Supervisors are a key component of PMICs and are used to monitor specific parameters, enabling the micro-controller to take corrective measures in case an event occurs. The XC6124A249MG-G is a low quiescent current and low voltage supervisor, used to detect voltage conditions in various applications.

Application field of XC6124A249MG-G

The XC6124A249MG-G is a low voltage and low quiescent current supervisor designed and manufactured by the Japanese company Torex. It is commonly used in notebooks, personal digital assistants (PDAs), and wearable electronic devices. This supervisor can also be used in automotive, industrial and consumer electronic applications. It is most suitable for applications that require a low power management system with very low quiescent current.

Working principle of XC6124A249MG-G

The XC6124A249MG-G is a Voltage Detector with Reset Output. It has two internal gold-coated reference voltages: the fixed VDD, and the adjustable VREF. It also has three outputs, Reset, Output & Power-On. This supervisor is used to detect voltage conditions in various applications. The XC6124A249MG-G compares the input voltage with the VREF voltage, and will output an active VDD level signal if the VREF voltage exceeds the set value. This output can be used to drive an FET for load protection, or as a reset signal for a microcontroller. It can also be used to turn on or off the power switch.

In order to reset the microcontroller, the reset output is connected to the reset pin of the microcontroller. If the VREF voltage exceeds the set value, the reset output will be switched to a logic low state and the microcontroller will be reset. This is necessary in order to prevent the microcontroller from stuck in an unpredictable state. The power-on output is also connected to the reset pin of the microcontroller. When the VREF voltage is within the set value, the power-on output will be switched to a logic high state and the microcontroller will be turned on.

The XC6124A249MG-G also has a High Input Voltage Detection (HVID) function which can be used to detect the input voltage. The HVID output is a logic low signal when the input voltage is higher than the VREF voltage. This output can be used to drive a transistor to protect the circuit from over-voltage. It can also be used as an output protection or as an over-voltage detection. The XC6124A249MG-G also has a Low Input Voltage Detection (LVID) function, which can be used to detect the input voltage. The LVID output is a logic low signal when the input voltage is lower than the VREF voltage.

The XC6124A249MG-G is a low quiescent current, low voltage supervisor and is used to detect voltage conditions in various applications. It has two internal gold-coated reference voltages: the fixed VDD, and the adjustable VREF. It also has three outputs, Reset, Output & Power-On. Additionally, it has a High Input Voltage Detection (HVID) and a Low Input Voltage Detection (LVID) function. The XC6124A249MG-G is commonly used in notebooks, PDAs, and wearable electronic devices, as well as in automotive, industrial and consumer electronic applications.
