The 8551401PA is a voltage reference IC (integrated circuit) with a wide range of potential applications. This two-pin integrated motor voltage regulator includes an on-chip precision voltage reference and two low-side or voltage droppedouts (MOSFETs) that are capable of sourcing up to 3A at 1 V. It is ideal for automotive,lighting,industrial,power management and other PMIC applications.

This voltage reference circuit is typically used to provide a regulated power supply voltage for an electronic load, for example an Industrial Control Unit (ICU) or motor. It is capable of driving loads up to 3A by providing a low voltage and has very low quiescent current consumption. The 8551401PA also features a low ripple current and a fast response time, which makes it particularly suitable for applications where a high-power supply is required with very short response times.

The 8551401PA can be used to precisely regulate the output voltage over a wide temperature range and is designed to work within a voltage range of 1.2V to 3.6V. This voltage reference circuit also has a maximum output current of 3 A and operates over a temperature range of -30°C to +85°C. It is also capable of providing a voltage drop of ≤100mV. In order to increase the accuracy of the output voltage, the 8551401PA utilizes two Precision Voltage Reference (PVR) inputs.

In order to ensure that the output voltage remains stable, the 8551401PA uses two MOSFETs to regulate the current supplied to the load. The two MOSFETs are electrically connected with one another, so the output current is split between them and the PVRs. The PVRs are used to monitor the input voltage and adjust the MOSFET gates to ensure that the correct output voltage is maintained. The 8551401PA also features an adjustable slew rate, which allows the output voltage to be held more accurately.

The 8551401PA is extremely versatile and can be used in a variety of applications, such as industrial control, lighting, and automotive electronics. Its low quiescent current requirement, wide temperature range and adjustable slew rate make it a perfect choice for applications where a precise voltage is required over a wide temperature range. Furthermore, its low ripple current characteristics and fast response time ensure that it is suitable for applications requiring high power with very short response times. In conclusion, the 8551401PA is an ideal voltage reference IC for a wide range of PMIC applications.
