The S-1004NA25I-I6T1U is a PMIC (Power Management Integrated Circuit) Supervisors. This product is designed for wide bandgap efficiency, protecting against inrush currents, and for automated sequencing of power up or down processes in power systems. It is ideal for use in applications in the consumer, industrial, automotive, and medical markets that require protection from over-current, over-voltage, and over-temperature events.

The S-1004NA25I-I6T1U is a 3.3V structural monitoring and switch circuit with a reset generator and comparator. It is a versatile device that provides a wide range of protection schemes and can be used to supervise and monitor systems up to 1.2V. It offers two channels of protection, one for over-current and the other for over-voltage. The current channel can be set to protect a ground or power source with any selected trip point between 1.2V and 3V. The over-voltage channel can be set with a trip point in the over-voltage monitoring range of 0.8V to 1.2V.

The S-1004NA25I-I6T1U is an ideal solution for protecting against inrush currents and providing efficient power distribution. It offers direct reset inputs, output enable/disable, and positive and negative current detection. The device also offers protection from over-temperature, with a minimum temperature threshold of -20°C. The reset signal is delayed for 10ms, ensuring a safe and slow start up of a system.

The current sensing comparator of the S-1004NA25I-I6T1U has three threshold configurations and is protected against Reverse Polarity Inrush (RPI). The user can configure the comparator thresholds to activate a fault flag prior to the reset signal being triggered. The reset signal will then trigger the protection switch, disabling the system in order to prevent any damage.

The output of the S-1004NA25I-I6T1U is an open-drain type with low current consumption that can be controlled ge, en/disable signal or reset internally via a delay timer. It also has an adjustable decay time for resetting the device when no fault is present so the system can return to normal power. This device is ESD protected and contains a short circuit protection circuit.

The S-1004NA25I-I6T1U is ideal for applications such as digital appliances, DC/DC converters, motor controllers, pre-engine controllers, automotive onboard power supplies and lighting control systems, USB power deliveries, and industrial control systems such as solar panels, HVAC systems, and servers. It is also suitable for use in medical applications such as patient monitoring systems, infusion pumps, and defibrillators.

In conclusion, the S-1004NA25I-I6T1U is a PMIC Supervisors designed for wide bandgap efficiency, protecting against inrush currents, and for automated sequencing of power up or down processes in power systems. The device is ideal for a wide range of applications from consumer to industrial, automotive, and medical applications, offering two channels of protection, direct reset inputs, output enable/disable, and multiple protection functions.
