VNH5050A-E STMicroelectronics

VNH5050A-E Automotive fully integrated H-bridge motor driver Features Type R I V DS(on) out ccmax 50 m max VNH5050A-E 30A 41V (per leg) PowerSSO-36 TP proprietary VIPower M0 technology that allows Output current: 30 A to efficiently integrate on the same die a true 3 V CMOS compatible inputs Power MOSFET with an intelligent Undervoltage and overvoltage shutdown signal/protection circuitry. The three dies are assembled in a PowerSSO-36 TP package on Overvoltage clamp electrically isolated lead frames. This package, Thermal shutdown specifically designed for the harsh automotive Cross-conduction protection environment offers improved thermal performance thanks to exposed die pads. Current and power limitation Moreover, its fully symmetrical mechanical design Very low standby power consumption allows superior manufacturability at board level. PWM operation up to 20 KHz The input signals IN and IN can directly A B interface to the microcontroller to select the motor Protection against loss of ground and loss of direction and the brake condition. The DIAG /EN A A V CC or DIAG /EN , when connected to an external B B Current sense output proportional to motor pull-up resistor, enables one leg of the bridge. current Each DIAG /EN provides a digital diagnostic A A Output protected against short to ground and feedback signal as well. The normal operating short to V condition is explained in the truth table. The CS CC pin allows monitoring the motor current by Package: ECOPACK delivering a current proportional to its value when CS DIS pin is driven low or left open. When Description CS DIS is driven high, CS pin is in high impedance condition. The PWM, up to 20 KHz, The VNH5050A-E is a full bridge motor driver allows to control the speed of the motor in all intended for a wide range of automotive possible conditions. In all cases, a low level state applications. The device incorporates a dual on the PWM pin turns off both the LS and LS A B monolithic high-side driver and two low-side switches. switches. All switches are designed using STMicroelectronics well known and proven Table 1.
