The SIP32461DB-T2-GE1 is a high-performance, fully integrated dual N-Channel MOSFET Power Distribution Switch with Output Load Drivers. This device is designed to provide primary negative side gate drive and current limiting control on each MOSFET, with a maximum gate drive voltage of 10.5 V. It is a power management integrated circuit (PMIC) particularly suited for high current applications.

The device features an idealized current-limited gate drive of up to 1.8 Amps. Its other features include a low RDS(on) of typically 3 milliohms for each MOSFET, internal thermal shutdown, soft-start, as well as overvoltage and overcurrent protection.

The SIP32461DB-T2-GE1 is primarily intended for applications such as automotive and industrial power distribution including High Voltage Direct Current (HVDC) power electronics, and DC-DC converter applications with a wide supply voltage range of 4.5 V to 17 V.

The device’s typical current limit is 1.8 Amps. The device has an adjustable voltage rail ranging from 4.5 V to 17 V to control the peak output current. The SIP32461DB-T2-GE1 also features integrated thermal shutdown protection, as well as a soft-start circuit to reduce system current spikes at startup.

The device’s two outputs can be connected in parallel for higher current capability up to a maximum of 4 Amps. The SIP32461DB-T2-GE1 is available in a 5 x 5 QFN package which is ideal for automotive and industrial applications where space is at a premium.

The SIP32461DB-T2-GE1’s working principle relies on two independent MOSFETs that are driven at opposite gate voltages in order to switch the power supply to the load. When the gate of a MOSFET is driven high, the switch is “on” and the power is supplied to the load. When the gate of a MOSFET is driven low, the switch is “off” and the power supply is disconnected from the load.

The integrated current-limited gate driver of the SIP32461DB-T2-GE1 limits the power dissipated in each MOSFET and ensures that higher currents are not applied. This helps to avoid overloading the MOSFET and provides improved protection for your system. The adjustable voltage rail allows the user to adjust the current limit and the output voltage in order to optimize performance. Additionally, the device has a thermal shutdown to protect the system in the case of an over-temperature condition.

In conclusion, the SIP32461DB-T2-GE1 is a high-performance, fully integrated dual N-Channel MOSFET Power Distribution Switch with Output Load Drivers. This device is intended for automotive and industrial applications where space is at a premium. Thanks to its high RDS(on) and adjustable voltage rail, this device provides improved performance with excellent protection against overvoltage and overcurrent conditions.
