7.2 STSPIN948 section
The STSPIN948 is a 4.5 A dual full-bridge driver for brushed DC motors or bipolar stepper motors. The power
stage is designed with high dynamic performance, allowing to achieve high frequency PWM control with precise
duty-cycle.
Each full-bridge is totally independent with a current limiter with adjustable threshold and OFF-time with slow or
mixed decay selection. Two amplifiers with fixed amplification factor are available for current sensing (using an
external shunt
resistor). The adjustable slew-rate guarantees the best trade-off between performances and EMI. Versatile power
stage offers several ways of operation for a high level of flexibility.
The device offers a complete set of protection features including overcurrent, overtemperature, and low bus
voltage detection.

7.3 Accelerometer and gyroscope: ISM330DHCXTR
The ISM330DHCXTR is a system-in-package featuring a high-performance 3D digital accelerometer and 3D
digital gyroscope tailored for Industry 4.0 applications. In the ISM330DHCXTR the sensing elements of the
accelerometer and of the gyroscope are implemented on the same silicon die, thus guaranteeing superior stability
and robustness.
The ISM330DHCXTR has a full-scale acceleration range of ±2/±4/±8/±16 g and a wide angular rate range of
±125/±250/±500/±1000/±2000/±4000 dps that enable its usage in a broad range of applications.
All the design aspects and the calibration of the ISM330DHCXTR have been optimized to reach superior
accuracy, stability, extremely low noise, and full data synchronization.
An unmatched set of embedded features (Machine Learning Core, programmable FSM, FIFO, sensor hub, event
decoding and interrupts) are enablers for implementing smart and complex sensor nodes which deliver high
performance at very low power.
The ISM330DHCXTR is available in a 14-lead plastic land grid array (LGA) package.
