TPS2112APWG4 is a Precision Voltage Supervisory and Tracking Controller from Texas Instruments (TI). This device is based on the TI TPS2112A family and is offered in a 1.9V to 10V operating voltage range, in a 4-pin package. It is designed with advanced low power technology and provides exceptional accuracy and low power consumption. Ideal for use in motor control, HVAC and other industrial applications, the TPS2112APWG4 is fully-featured and provides the user with a variety of advantages.

TPS2112APWG4 belongs to PMIC - OR Controllers, Ideal Diodes class of products from TI. PMIC, or power management integrated circuit, is any integrated circuit chip used to manage and regulate the electrical power of a device. OR Controllers are specialized ICs used to generate and control the physical movement of a mechanical device, such as a motor. Ideal Diodes are ideal diode controllers that maintain the voltage between two input and output pins at a desired value.

The TPS2112APWG4 features 24-bit voltage-tracking accuracy with a mismatch of ± 0.25% or ± 10 mV. Its Precision Booster will exact the desired tracking level and its Accuracy Booster Amplifier provides precise tracking accuracy and outstanding line and load transient performance. It also features a Thermal Proximity Timer which helps to optimize system performance by controlling the switching of clock frequencies.

Its working principle is based on the architecture used in the TPS2112A family. It uses an internal voltage reference and operational amplifier to generate accurate tracking voltages. The operational amplifier controls the output voltage by varying the control voltage provided from the voltage reference. An external resistor divider can be used to program the output voltage and to regulate the output current. When the input voltage is applied, the internal circuit will adjust the output voltage so that it tracks the input voltage with accuracy.

The TPS2112APWG4 is suitable for applications such as motor control, HVAC, industrial, and consumer equipment. In motor control applications it is used as a controller for a DC brushless/brush dc motor. It can also be used as a voltage tracking device for non-isolated power supplies or switch mode power supplies. In HVAC systems, the TPS2112APWG4 can be used to provide precise control of fan speeds, compressor speed and motor speed. In consumer equipment, the TPS 2112A can be used to regulate the charging and discharging of batteries or to provide fail-safe protection against over-voltage, under-voltage and over-current conditions.

With its temperature (up to +125°C), voltage and current regulation, the TPS2112APWG4 provides excellent performance and accuracy in a wide range of applications. It is an easy to use, low power solution for any application requiring precision voltage regulation and tracking.
