The XC6121C233MG-G is classified as a PMIC-Supervisor. It is specifically designed for a wide range of applications requiring reliable electrical system supervision and multiple output voltages. This power management integrated circuit provides a comprehensive system power-on reset or brownout detection, voltage monitoring, and independent voltage system reset to protect and prevent system damage due to uncontrolled situations. In addition, it offers many other advanced features such as programmable manual reset, window watchdog timer, signal margin tracking, and a wide operating temperature range.
The XC6121C233MG-G provides reliable system power-on reset (POR) or brownout detector (BOD). POR is designed to ensure correct system initialization every time the system powers up, while BOD ensures stable operation during power faults and avoids system malfunction as a result of low-voltage inputs. The POR and BOD are both programmable and have same or different trigger thresholds, which can be adjusted by external resistors. The device can also be used as a voltage supervisor providing voltage fault detection, range checking and latch-off function. In order to ensure wide fault coverage, multiple input voltages can be monitored and set-up with independent upper or lower Vcc trip points.
The XC6121C233MG-G also provides window watchdog timer (WWD) with programmable reset duration. This watchdog timer consists of two independent counters, a start counter and an end counter. Upon receiving a pulse input from the system, the start counter is activated and counts down until it reaches 0. When the start counter has reached 0, the end counter is triggered and begins counting down. If the system does not provide a pulse input before the end counter reaches 0, then the device will reset the system. The pulse width and pulse period are both programmable and the WWD is configurable as windowed or single-shot modes.
In addition to the watchdog timer, the XC6121C233MG-G also provides programmable manual reset. This reset is triggered through a logic signal, and it can be designed to reset the system or just the power-down output stream. It can be used to reboot the system when a fault or unexpected condition is detected. The device also offers signal margin tracking, which allows the user to configure the margin in order to protect the system against unexpected input signal changes.
The XC6121C233MG-G is designed for multiple industrial and automotive applications such as mobile phones, batteries and other communication systems, as well as for automatic black-box applications. The device has an operating voltage range of 3.3V to 5.5V and supports -40 °C to 125 °C operating temperature range. It is manufactured in a very small 5-pin, SOT23 package, making it ideal for space-constraint applications.
In summary, the XC6121C233MG-G is a PMIC-Supervisor designed for a wide range of applications. It integrates a comprehensive system power-on reset or brownout detection, voltage monitoring and independent voltage system reset to protect the system. Additional features include programmable manual reset, window watchdog timer, signal margin tracking and wide operating temperature range. It is designed to take up minimal board space and is ideal for space-constraint applications.
