Power management integrated circuits (PMICs) are essential components of modern electronic designs. Supervisors and voltage monitors are used to monitor and protect communication interface, memory or processor related components from potential losses due to overvoltage or overcurrent. The LM3708XQTP-308/NOPB is a supervisor and voltage monitor belonging to the popular SUperBLIN Family of ICs.

The LM3708XQTP-308/NOPB is designed to provide system monitoring, reset and power-on reset functions. Its principal feature is a push button debounce circuit which enables low pulsed noise immunity. The push button debounce feature can be used to reset any component in the system or power up the system when pressed.

The LM3708XQTP-308/NOPB features two voltage supervisors that monitor system voltages. The Reset Active Level is an output which provides an active low signal whenever either supervisor\'s threshold is exceeded. The Reset Active Level has an adjustable threshold that can be programmed via I2C. The Push-Button Debounce can be set to different widths, thus providing different reset times from the system.

TheLM3708XQTP-308/NOPB has a low start-up current requirement of 10µA and a low quiescent current of 4µA at 300kHz operation. It also has a Shutdown supply current of 0.1µA which is required when the supervisor is disabled or the supply voltage falls below the minimum threshold. This makes it ideal for applications where low power consumption is critical.

The LM3708XQTP-308/NOPB has excellent noise immunity and a built-in noise filter with adjustable detection sensitivity that can detect external noise up to 120dBVrms. This makes it suitable for industrial and automotive applications where noise immunity is a key concern.

The LM3708XQTP-308/NOPB also features a self-discharge protection circuit to ensure accurate monitoring of system voltages. The circuit monitors the voltage level at the input pins of the device and shuts down itself whenever the input voltage drops below the minimum threshold. This allows the system to remain in a safe condition without draining its power source.

The LM3708XQTP-308/NOPB is ideal for industrial, automotive and consumer applications that need accurate system monitoring, reset and power-on reset. It is also suitable for embedded systems that place a priority on low power consumption. With its excellent noise immunity and self-discharge protection circuit, the LM3708XQTP-308/NOPB is a simple yet reliable solution to protect your system from potential losses due to overvoltage or overcurrent.
