|Part||NCP81239MNTXG New Technology|
|Title||Switching Controllers I2C CONFIGURABLE 4 SWITCH|
ON Semiconductor NCP81239 4-Switch Buck-Boost Controller is designed for converting battery or adapter voltage into supply rails. The NCP81239 controller is fully compliant with the USB Power Delivery Specification when used in collaboration with a USB PD or CType Interface Controller. The USB Power Delivery (PD) Controller drives 4 NMOSFET switches which buck or boost and provide role swap function. The role swap function is specified in the USB Power Delivery Specification which is excellent for all USB PD applications. The buck-boost controller has an operating supply and load range of 4.5V to 28V. The NCP81239 is developed for applications requiring dynamically controlled slew rate limited output voltage. The slew rate limited output voltage requires either voltage higher or lower than the input voltage. The 4-switch buck-boost controller has an I2C interface.

The NCP81239 USB Power Delivery (PD) Controller is a synchronous buck boost that is optimized for converting battery voltage or adaptor voltage into power supply rails required in notebook, tablet, and desktop systems, as well as many other consumer devices using USB PD standard and C-Type cables. The NCP81239 is fully compliant to the USB Power Delivery Specification when used in conjunction with a USB PD or C-Type Interface Controller. NCP81239 is designed for applications requiring dynamically controlled slew rate limited output voltage that require either voltage higher or lower than the input voltage. The NCP81239 drives 4 NMOSFET switches, allowing it to buck or boost and support the consumer and provider role swap function specified in the USB Power Delivery Specification which is suitable for all USB PD applications. The USB PD Buck Boost Controller operates with a supply and load range NCP81239A is functionally same as NCP81239 except with different I2C address.

Figure 3. Block Diagram Table 1. PIN FUNCTION DESCRIPTION
Pin Name HSG1 LSG1 PGND V1 CS1 CLIND SDA SCL INT CFET Description S1 gate drive. Drives the S1 N-channel MOSFET with a voltage equal to VDRV superimposed on the switch node voltage VSW1. Drives the gate of the S2 N-channel MOSFET between ground and VDRV. Power ground for the low side MOSFET drivers. Connect these pins closely to the source of the bottom N-channel MOSFETs. Negative terminal of the current sense amplifier. Positive terminal of the current sense amplifier. Input voltage of the converter Current sense amplifier output. CS1 will source a current that is proportional to the voltage across to an external resistor. CS1 voltage can be monitored with a high impedance input. Ground this pin if not used. Open drain output to indicate that the or CS2 voltage has exceeded the I2C programmed limit. I2C interface data line. I2C interface clock line. Interrupt is an open drain output that indicates the state of the output power, the internal thermal trip, and other I2C programmable functions. Controlled drive of an external MOSFET that connects a bulk output capacitor to the output of the power converter. Necessary to adhere to low capacitance limits of the standard USB Specifications for power prior to USB PD negotiation. The ground pin for the analog circuitry. Output of the transconductance amplifier used for stability in closed loop operation.
