Power components are critical components in any system, such as consumer electronics, automotive applications, and even medical applications. In order to maximize system reliability and efficiency, it is important to use the right power management integrated circuit (PMIC) for a given application. One such PMIC is the S-80932CNPF-G82TFU, which belongs to the family of supervisors. This section will analyze the application field and working principle of the S-80932CNPF-G82TFU.

The S-80932CNPF-G82TFU is a PMIC supervisory circuit designed to support high-reliability applications requiring uninterrupted power supply, without the need for manual reset control. It is designed for automotive applications, medical equipment, as well as industrial and consumer applications. The IC has an operating temperature range of -40 to +105°C, a single supply voltage of 4.5 V to 3.6 V, and an extended supply voltage of 5.5 V to 2.7 V. It is also rated at a maximum current of 6 mA. The S-80932CNPF-G82TFU provides both active-high RESET and active-low RESET capabilities, with both signals synchronized to the rising edge of VDD.

The S-80932CNPF-G82TFU includes two internal temperature compensated POR, one active-high POR, and one active-low POR. Both POR signals are synchronized to the rising edge of VDD. The active-high POR (PORH) monitors the system power supply and reset the system when the power supply voltage drops below its undervoltage threshold (<3.3 V). The active-low POR (PORL) monitors the parallel logic voltage and reset the system when the logic voltage drops below its undervoltage threshold (<1.7 V).

The S-80932CNPF-G82TFU also includes an internal temperature compensated and voltage-regulated Power On Reset (POR). The POR output is synchronized to VDD and is asserted when the POR input voltage Cc reaches the reset threshold. The Cc pin measures the system\'s capacitance and adjusts the POR reset threshold accordingly. The internal reset circuit monitors the system power supply and will assert a reset when the power supply voltage drops below the minimum VDD threshold, typically around 4.5 V. The S-80932CNPF-G82TFU also includes a watchdog timer that can be used to generate a watchdog alert if the system is not executing the reset sequence within a predetermined time period.

The S-80932CNPF-G82TFU includes an adjustable overvoltage detection threshold and an overvoltage alarm output pin. The overvoltage detection logic monitors the VDD power supply and generates an active-high alarm signal when the power supply voltage exceeds the overvoltage threshold. The S-80932CNPF-G82TFU also includes an external power-on reset pin that can be used to reset the system when the power supply voltage rises beyond the minimum reset threshold.

The S-80932CNPF-G82TFU also includes a programmable voltage monitoring circuit that can be used to generate an active-low POR output when the system power supply voltage drops below the minimum reset threshold. The voltage monitoring circuit can be configured for an adjustable voltage limit and an adjustable time delay for the undervoltage detection. The S-80932CNPF-G82TFU also includes a power down reset function that can be used to assert a reset when the system power supply voltage drops below a certain threshold.

In summary, the S-80932CNPF-G82TFU is a PMIC supervisor circuit designed for automotive, medical, industrial, and consumer applications. It includes multiple temperature-compensated reset circuits, an adjustable overvoltage detection circuit, and a programmable voltage monitor. The S-80932CNPF-G82TFU can be used to ensure uninterrupted system operation and consistent performance in high-reliability applications.
