UTP28SP30OR is a sensitive, low voltage DC powered solid-state PWM governor. It is designed for use in electronic speed control applications involving electric vehicles and onboard motor motor control systems.

This product of Maxim Integrated is a monolithic integrated circuit which is ideally suited for controlling variable speed DC brush and brushless motor applications. The UTP28SP30OR features high efficiency, low ripple, quick action response and provides superior motor control performance over a wide range of speed and load conditions.

The UTP28SP30OR is composed of CMOS transistors fabricated on a high frequency process and has high efficiency and low operating current requirements. The maximum operating voltage is 28 volts. The power transistors are capable of switching currents up to 30 A. It reliably controls up to 5 kW of power at 60V. It can be used in a variety of applications, including generators, electric power tools, electric vehicles, and electric scooters, among others.

The UTP28SP30OR is designed to accept a DC power supply and a reference speed signal between 0 and 5V. The reference speed signal is processed through the internal signal conditioning circuitry and is converted to a Pulse Width Modulation (PWM) signal, which is then applied to the gate of a power transistor. The transistor then controls the output current signal of the UTP28SP30OR, which is a direct proportional representation of the reference speed signal.

The UTP28SP30OR includes built-in over-voltage and over-current protection circuits to prevent damage to the motor and other components. The internal signal conditioning circuitry can be optimized to the user\'s requirements. The device can be configured for both current-mode and voltage-mode operation. It also includes a temperature sensor, which can be used to monitor the heat dissipation of the device.

Overall, the UTP28SP30OR is a versatile and efficient motor control product that is capable of providing superior performance in a wide range of applications. It is an ideal choice for designing motor controllers due to its low operating current requirements, high efficiency, and low ripple. The built-in protective circuits also protect against over-voltage and over-current conditions, making it suitable for use in environments that may be prone to electromagnetic interference.
