STSPIN830/BKN STMicroelectronics

STSPIN830 Compact and versatile three-phase and three-sense motor driver Datasheet - production data Applications Industrial robotics Medical and health care Factory automation end-points Home appliances Small pumps Server, computing and general purpose FANs QFN 4 x 4 - 24 lead Office and home automation Description Features The STSPIN830 is a compact and versatile field oriented control FOC ready three-phase motor Operating voltage from 7 to 45 V driver. It integrates in a very small 4 x 4 mm QFN Maximum output current 1.5 A rms package, both the control logic and a fully R HS + LS = 1 typ. DSon protected low R triple half-bridge power DSon stage. Supporting both single and three shunts architectures Thanks to a dedicated MODE input pin the device Current control with adjustable OFF time offers the freedom to decide whether to drive it through 6 inputs (one for each power switch) or a Current sensing based on external shunt more common 3 PWM direct driving inputs. resistors The STSPIN830 supports both single and three Flexible driving methodology user settable shunts architectures and embeds a PWM current between 6 inputs (high side and low side controller based on user settable values of driving) and 3 inputs (direct PWM driving) reference voltage and OFF time. FOC compatible thanks to three shunts sensing topology support The devices can be forced in a low consumption state reducing the total current consumption down Full protections set to less than 45 A. Non-dissipative overcurrent protection As with all other devices from the STSPIN family, Short-circuit protection the STSPIN830 integrates a complete set of Undervoltage lockout protections for the power stages (non-dissipative Thermal shutdown overcurrent, thermal shutdown, short-circuit, Interlocking function undervoltage lockout and interlocking) making it a Low standby current consumption bulletproof solution for the new wave of demanding industrial applications.
