VNH3ASP30-E STMicroelectronics

VNH3ASP30-E Automotive fully integrated H-bridge motor driver Datasheet - production data side switches. The HSD switch is designed using STMicroelectronics proprietary VIPower M0 technology that efficiently integrates a true Power MOSFET with an intelligent signal/protection circuit on the same die. The low-side switches are vertical MOSFETs manufactured using STMicroelectronics proprietary EHD (STripFET) process.The MultiPowerSO-30 three circuits are assembled in a MultiPowerSO-30 package on electrically isolated lead frames. This package, specifically designed Features for the harsh automotive environment, offers improved thermal performance thanks to exposed Type R I V DS(on) out ccmax die pads. Moreover, its fully symmetrical mechanical design provides superior 42 mmax VNH3ASP30-E 30 A 41 V manufacturability at board level. The input signals per leg) IN and IN can directly interface with the A B microcontroller to select the motor direction and the brake condition. Pins DIAG /EN or A A AEC-100 qualified DIAG /EN , when connected to an external pull- B B up resistor, enable one leg of the bridge. They 5 V logic level compatible inputs also provide a feedback digital diagnostic signal. Undervoltage and overvoltage shutdown The normal condition operation is explained in the Overvoltage clamp truth table. The CS pin monitors the motor current by delivering a current proportional to its value. Thermal shut down The speed of the motor can be controlled in all Cross-conduction protection possible conditions by the PWM up to 20 kHz. In Linear current limiter all cases, a low level state on the PWM pin will turn off both the LS and LS switches. When Very low standby power consumption A B PWM rises to a high level, LS or LS turn on A B PWM operation up to 20 kHz again depending on the input pin state. Protection against loss of ground and loss of V CC Table 1.
