Here is a detailed breakdown of the 20-pin configuration and corresponding pin functions of the VNH3SP30TR-E:
Pin No. Pin Name Description 1 VCC Positive supply voltage input for the power switch (typically 12V to 36V for automotive applications). 2 GND Ground connection. 3 OUT Output to the load. This pin connects to the motor or other actuated load. 4 OUT Output to the load (second pin for dual-output configuration). 5 VBOOT Bootstrapping capacitor connection for high-side driver. Ensures proper switching for the internal MOSFETs . 6 VCC Additional supply pin to support the power switch functionality (same as pin 1). 7 N.C. No connection (reserved for internal functions). 8 VSTBY Standby input. When this pin is low, the device enters a low-power state. 9 IN Input pin for motor control logic, typically used for speed or direction control. 10 IN Input pin for motor control logic (second pin for dual-input configuration). 11 DIAG Diagnostic output pin for failure detection (e.g., over-temperature, overcurrent, etc.). 12 DIAG Diagnostic output pin (second pin for dual-output configuration). 13 VREG Voltage regulator output for supplying the gate drivers (internal 5V voltage regulator). 14 GND Ground connection (second pin for dual-ground configuration). 15 OUT Output to the load (third pin for a triple-output configuration). 16 OUT Output to the load (fourth pin for a quadruple-output configuration). 17 VCC Positive supply voltage input for the power switch (same as pin 1). 18 GND Ground connection (same as pin 14). 19 SENSE Sense input for monitoring current or other system parameters (e.g., motor current feedback). 20 N.C. No connection (reserved for internal functions).Explanation of Each Pin Function:
VCC: Supplies the necessary voltage to operate the device. It powers the internal logic and high-side MOSFETs. GND: Ground reference for the device's operation. OUT: The pin connected to the motor or actuator being controlled. It provides the switched voltage/current to the load. VBOOT: Used to ensure the proper operation of the high-side MOSFET by charging a bootstrap capacitor. VSTBY: If this pin is set low, the device enters standby mode, significantly reducing current consumption. IN: Input control signal for setting the state of the switch. It can control direction, speed, or other parameters. DIAG: Diagnostic feedback used to report errors or failures, such as over-temperature or overcurrent conditions, for safety monitoring. VREG: A voltage regulator output used to supply power to gate drivers for the internal MOSFETs. SENSE: Provides feedback about the current flowing through the switch or load, often used for overcurrent protection or control loops.FAQ: Common Questions about the VNH3SP30TR-E
