3 / 26 page 3/26 VNH2SP30-E Table 3. Pin Definitions And Functions Note: (*) GNDA and GNDB must be externally connected together Table 4. Pin Functions Description Pin No Symbol Function 1, 25, 30 OUTA, Heat Slug2 Source of High-Side Switch A / Drain of Low-Side Switch A 2,4,7,12,14,17, 22, 24,29 NC Not connected 3, 13, 23 VCC, Heat Slug1 Drain of High-Side Switches and Power Supply Voltage 6ENA/DIAGA Status of High-Side and Low-Side Switches A; Open Drain Output 5INA Clockwise Input 8 PWM PWM Input 9 CS Output of Current sense 11 INB Counter Clockwise Input 10 ENB/DIAGB Status of High-Side and Low-Side Switches B; Open Drain Output 15, 16, 21 OUTB, Heat Slug3 Source of High-Side Switch B / Drain of Low-Side Switch B 26, 27, 28 GNDA Source of Low-Side Switch A (*) 18, 19, 20 GNDB Source of Low-Side Switch B (*) Name Description VCC Battery connection. GNDA GNDB Power grounds, must always be externally connected together. OUTA OUTB Power connections to the motor. INA INB Voltage controlled input pins with hysteresis, CMOS compatible. These two pins control the state of the bridge in normal operation according to the truth table (brake to VCC, Brake to GND, clockwise and counterclockwise). PWM Voltage controlled input pin with hysteresis, CMOS compatible.Gates of Low-Side FETS get modulated by the PWM signal during their ON phase allowing speed control of the motor ENA/DIAGA ENB/DIAGB Open drain bidirectional logic pins.These pins must be connected to an external pull up resistor. When externally pulled low, they disable half-bridge A or B. In case of fault detection (thermal shutdown of a High-Side FET or excessive ON state voltage drop across a Low-Side FET), these pins are pulled low by the device (see truth table in fault condition). CS Analog current sense output. This output sources a current proportional to the motor current. The information can be read back as an analog voltage across an external resistor. |
