The CAT1025LI-30-G is a member of an advanced family of low power supervisory systems used in a wide variety of applications. The CAT1025LI-30-G is a precision three-channel supervisor with two independent outputs, ideal for monitoring and controlling system voltages and temperatures. The CAT1025LI-30-G includes an internal voltage regulator, and the two outputs can be programmed to provide independent reset or active-low and active-high signals for multiple functions.

The CAT1025LI-30-G is primarily used in embedded systems, industrial and consumer electronics, automotive applications, and white goods applications. It is designed with a power-on reset (POR) circuit, an external reset (ER) circuit, a reset-/undershoot-monitoring circuit, an open-drain output, and a watchdog monitor circuit. The CAT1025LI-30-G has a monitoring range of 4.5V to 6.2V, a temperature range of -20°C to +80°C, and a watchdog timer with a 2.5 - ±0.3 sec delay (maximum).

The CAT1025LI-30-G is suitable for systems that require low-power operation, low power consumption, and fast reaction times. It also offers tolerance to high levels of noise and wide temperature ranges due to its high integration level. The two outputs can be programmed to provide a power-on reset (POR), an external reset (ER), an open-drain output, and a watchdog monitor circuit. The CAT1025LI-30-G also offers a unique temperature sensor for monitoring internal temperatures.

The CAT1025LI-30-G is designed with a power-on reset (POR) circuit, an external reset (ER) circuit, a reset-/undershoot-monitoring circuit, and a watchdog monitor circuit. It also has an input voltage range of 4.5-6.2V, a temperature range of -20°C to +80°C, and a watchdog timer that provides a maximum of 2.5-±0.3 sec delay. The main purpose of the power-on reset (POR) circuit is to ensure proper initialisation of the system when it is powered on after a power-down event.

The external reset circuit is important for controlling the reset signal for cores in the system since it is independent from the power-on reset and can be applied at any time. The reset-/undershoot-monitoring circuit monitors the in-circuit voltage drops below the acceptable operating voltage levels, and the watchdog monitor circuit will reset the system when it detects a failure due to device or system malfunction.

The CAT1025LI-30-G also provides protection from over-current, over-voltage, and over-temperature conditions. This circuit utilizes over-current and over-voltage protection circuits to monitor the digital supply pin and the analog output pins of the load. The over-temperature circuit is used to monitor the temperature of the load by comparing the actual temperature to the pre-programmed safe temperature. It will reset the system when the temperature exceeds the pre-programmed limit.

The CAT1025LI-30-G is a multi-channel supervisor designed to monitor and control multiple systems safely and efficiently. It offers a complete range of reset options with its two independent outputs, and it provides protection against various faults in order to ensure minimal downtime and disruption to system operations. It is also a low power device, allowing it to be used in system applications where power consumption is of key concern.
