VNH5180A-E STMicroelectronics

VNH5180A-E Automotive fully integrated H-bridge motor driver Features Type R I V DS(on) out CCmax 180 m max VNH5180A-E 8A 41V (per leg) PowerSSO-36 TP Output current: 8 A proprietary VIPower M0 technology that allows 3 V CMOS compatible inputs to efficiently integrate on the same die a true Undervoltage shutdown Power MOSFET with an intelligent Overvoltage clamp signal/protection circuitry. The three dies are assembled in PowerSSO-36 TP package on Thermal shutdown electrically isolated leadframes. This package, Cross-conduction protection specifically designed for the harsh automotive Current and power limitation environment offers improved thermal performance thanks to exposed die pads. Very low standby power consumption Moreover, its fully symmetrical mechanical design PWM operation up to 20 KHz allows superior manufacturability at board level. Protection against loss of ground and loss of The input signals IN and IN can directly A B V CC interface to the microcontroller to select the motor direction and the brake condition. The Current sense output proportional to motor DIAG /EN or DIAG /EN , when connected to an current A A B B external pull-up resistor, enables one leg of the Output protected against short to ground and bridge. Each DIAG /EN provides a feedback A A short to V CC digital diagnostic signal as well. The normal Package: ECOPACK operating condition is explained in the truth table. The CS pin allows to monitor the motor current by delivering a current proportional to its value when Description CS DIS pin is driven low or left open. When The VNH5180A-E is a full bridge motor driver CS DIS is driven high, CS pin is in high intended for a wide range of automotive impedance condition. The PWM, up to 20 KHz, applications. The device incorporates a dual allows to control the speed of the motor in all monolithic high-side driver and two low-side possible conditions. In all cases, a low level state switches. Both switches are designed using on the PWM pin turns off both the LS and LS A B STMicroelectronics well known and proven switches. Table 1.
