The AAT4610BIGV-T1 is an integrated power management application specific integrated circuit (ASIC) that provides a versatile and flexible power switch solution for a variety of low voltage, high current applications. The device is composed of a power switch, load driver, and on-chip logic circuits, offering numerous features not available with traditional solutions.

Features of the AAT4610BIGV-T1 include the following:

• High efficiency power switch.
• Low RDSon (resistance) for low voltage and high current applications.
• Extremely low Vsw (reverse breakdown voltage) for improved efficiency at high current loads.
• High ESD protection of up to +3500V.
• 5V tolerant I/O.
• 595mV typical on-state drop with low gate charge.
• Wide operating temperature range of -40 to +85°C.

The AAT4610BIGV-T1 is suitable for high-side power switch applications such as DC-DC converters, point of load (PoL) regulators, high/low side switches, and hot-swap solutions. It can also be used as an on/off switch in switches and relays, or as a load driver in automotive DC power systems.

The AAT4610BIGV-T1 includes an on-chip gate drive circuit and over-voltage protection, eliminating the need for large external gate drive components. This lowers overall system cost and reduces board space. In addition, the device has an enable input that can be used to turn off the switch when it is not in use. This can be used for energy savings and/or for protection in cases when the switch needs to be disabled.

The AAT4610BIGV-T1 is designed to operate from a 3.3V logic supply, which offers the advantage of lower gate drive operating voltage and thus higher efficiency for the power switch. The device also features an adjustable over-voltage protection input, which allows the user to set the trip point for over-voltage protection.

The AAT4610BIGV-T1 operates with a simple two-wire (input & output) interface, which eliminates the need for complicated wiring schematics. This allows for a simplified power system design, making it easier to scale up to a higher voltage and current rating system. The device also supports a synchronous rectification mode, which improves efficiency and reduces overall system power consumption.

In summary, the AAT4610BIGV-T1 is an integrated power management ASIC that offers a versatile and flexible power switch solution for a variety of low voltage, high current applications. It includes an on-chip gate drive circuit and over-voltage protection, eliminating the need for large external gate drive components. It is suitable for high-side power switch applications such as DC-DC converters, point of load (PoL) regulators, high/low side switches, and hot-swap solutions. It also features a 5V tolerant I/O, wide operating temperature range of -40 to +85°C, and adjustable over-voltage protection input.
