The S-80939CLPF-G69TFU is a low-power, micro-power supply voltage supervisor that is specifically designed for automotive applications. It belongs to the PMIC (Power Management IC) - Supervisor category. It is ideal for applications that require low power consumption and ideal power supply voltage management.

The S-80939CLPF-G69TFU is a high performance micro-power supply voltage supervisor with overcurrent protection, programmable reset delay, active-high/active-low reset pin, and an adjustable reset threshold voltage range. The device features a chip enable input, power-on reset, watchdog timer, and a programmable supply voltage level which enables the user to select the best power supply voltage range for the intended application. The device also features a CompB output that is used to detect an out-of-range condition before an error occurs.

The S-80939CLPF-G69TFU is based on a simple charge pump design. Its operating principle is simple - when the power supply voltage (Vdd) is below a certain reference voltage or the voltage drop across the current sense resistor reaches a certain threshold, the current sensing logic initiates reset and disables the microcontroller. Depending on the setting of the application soft start or reset configuration, the reset output will be either active-high or active-low. The device can be programmed to have a reset delay of up to 8 seconds, which can prevent false reset signals due to momentary power supply voltage drops or transients.

The S-80939CLPF-G69TFU device is suitable for automotive applications due to its low power consumption and wide operating voltages. It is also stable and economy friendly as it only draws micro-amps to maintain its functionality. The device can be used in a variety of applications, such as voltage regulation, power supply sequencing and reset control. It can be used in microprocessors, microcontrollers, embedded systems, and power management applications. It is also applicable in electrical systems that require a reliable power-on reset feature, such as emergency lighting systems, wireless communication systems, and automotive applications.

Overall, the S-80939CLPF-G69TFU is a high performance low-power micro-power supply voltage supervisor that is specifically designed for automotive applications. Its sophisticated design and wide operating voltage range make it an ideal choice for automotive applications. Its active-high/active-low reset pin, programmable reset delay, and adjustable reset threshold make it highly adjustable for different application requirements. Its advanced current sensing technology allows for excellent stability and low power consumption.
