ST VNH5050ATR-E

VNH5050A-E is a full-bridge motor driver designed for a wide range of automotive applications. The device integrates dual monolithic high-side drivers and two low-side switches. All switches are designed using a well-established proprietary technology that enables efficient integration of true power MOSFETs and intelligent signal/protection circuits on the same die. Three chips are assembled in a PowerSSO-36 TP package, which is specifically designed for harsh automotive environments and provides enhanced thermal performance through exposed die pads. In addition, its fully symmetrical mechanical design offers superior board-level manufacturability. Input signals INA and INB interface directly with a microcontroller to select motor direction and braking state. When DIAG A/EN A or DIAG B/EN B is connected to an external pull-up resistor, the corresponding arm of the bridge is enabled. Each DIAG A/EN A also provides a digital diagnostic feedback signal. Normal operating conditions are described in the truth table. When the CS_DIS pin is driven low or left open, the CS pin monitors motor current by sourcing a current proportional to the motor current. When CS_DIS is driven high, the CS pin enters a high-impedance state. PWM frequency up to 20kHz enables motor speed control under all possible conditions. In all cases, a logic-low state on the PWM pin turns off the LSA and LSB switches.
