UCC5639FQPTR is a low-cost, high-performance, single-chip controller and Power MOSFET terminals with differential buffers and forward-looking diode protection. It is designed for applications where a wide range of input voltages or varying output voltages is required and where the application demands high control accuracy, flexibility, and easy programming.

The UCC5639FQPTR is particularly suitable for interfacing between logic circuits and power MOSFETs, providing an excellent combination of low-cost, high precision, low-power dissipation, and high reliability. The UCC5639FQPTR includes two independent buffered logic outputs, a High-side and a Low-side low-impedance output capable of driving up to 1 ampere of load current.

The UCC5639FQPTR integrates one N-Channel MOSFET and one P-Channel MOSFET on-chip, with forward-looking diode-protection integrated on-chip. These MOSFETs are used to control the power that is provided to the load. This feature relieves the system designer from the burden of having to source additional power FETs. The MOSFETs are capable of switching voltages up to 18V.

The UCC5639FQPTR also features an adjustable current-sense attenuator that allows the user to set the de-emphasis threshold (or pin-voltage thresholds) which triggers an output transition when the input voltage falls within the set parameters. This is used for precision control of the output voltage and load current on applications that require high accuracy and/or performance. The UCC5639FQPTR also includes a low-threshold absorber that reduces the static dissipation of the power FETs when used in applications with an uncontrolled power supply.

Another feature of the UCC5639FQPTR is its bidirectional buffered input. The buffered input provides higher accuracy signals to the controller and allows the user to easily switch the analog signals between direct and buffered outputs. The buffered input eliminates ground-bounce effects and reduces noise in the system.

The UCC5639FQPTR is also well-suited for use in automotive applications where it can be used to drive high-side and low-side power FETs with a single capacitor-less controller. The controller’s integrated ESD protection reduces the noise on the power lines and allows the device to be used in noisy environments. The integrated thermal-shutdown feature is also provided for thermal protection purposes.

Ferroelectric random access memory (FRAM) can also be used with the UCC5639FQPTR. FRAM is an ideal solution for applications that require non-volatile memory that can be efficiently updated in a very short period of time. The UCC5639FQPTR supports an input voltage range of up to 14.7V to support efficient operation in a wide range of applications and environments.

In terms of applications, the UCC5639FQPTR is well-suited for use in any application where high-speed switching, high-accuracy control, and low-power dissipation are all required. This includes lighting, motor control, power supply, computing, and signal replacement applications. Additionally, the differential buffering feature of the UCC5639FQPTR makes it an excellent choice for applications that require wide ranging input voltage and signal isolation.

In summary, the UCC5639FQPTR is an excellent option for interfacing between logic and power MOSFETs. Its integrated power FETs and ESD protection, along with its current-sense attenuator and low-threshold absorber, make it an ideal choice for a variety of application fields. Additionally, its wide input voltage range and differential buffering capabilities make it an attractive solution when precision and signal isolation are both required.
