TI MSP430FR2433IRGER TIDA-01588 Power Stage DC Servo Drive Design
Texas Instruments' TIDA-01588 Power Stage DC Servo Drive Design
The most commonly used vibration sensors in industrial environments are integrated electronic piezoelectric (IEPE) sensors. At the heart of this reference design (Figure 4) is a complete analog front end for IEPE sensor interface. This design demonstrates that low-power, flexible, high-resolution, high-speed conversion of IEPE sensor data can be achieved in a small form factor solution

MSP430FR2433IRGER: This is TI's ultra-low-power FRAM-based MSP430FRx microcontroller family with the lowest power consumption and integrated peripherals to support a wide range of low-power and portable applications. These MCUs are ideal for applications where the MCU operates primarily in standby mode. The FRAM-based MSP430FRx MCU family recently added options for scalable data logging and security features. Housed in a small VQFN package (4 mm × 4 mm), the MSP43FR2433 is ideal for small form factor industrial sensors and combines a variety of integrated peripherals in addition to ultra-low power consumption.
The TPS70933DRVR series linear regulators feature ultra-low quiescent current, making them ideal for power-sensitive applications. These devices use a precision bandgap and error amplifier with 2% accuracy over the operating temperature range. Quiescent current is as low as 1 μA, making these devices an ideal solution for battery-powered, always-on applications with very low idle-state power consumption. This family of devices has additional safety features including thermal shutdown, current limiting and reverse current protection.
The DRV8870DDAR, is a brushed DC motor driver from TI that can be used in applications such as industrial equipment, appliances, printers and other small machines. Two logic inputs control four N-channel MOSFET H-bridge motor drivers for bidirectional motor control with 3.6 A peak current. To control motor speed, the input can be pulse width modulated with an optional current decay mode. When both inputs are set low, the device enters a low-power sleep mode. The DRV8870 also integrates current regulation based on the VREF analog input and pin ISEN voltage from an external sense resistor through which the motor current flows. The device limits current to known levels, greatly reducing system power requirements and the bulk capacitors needed to maintain motor voltage regulation, especially during start-up and stall conditions.
MSP430FR2433IRGER: This is TI's bidirectional TVS ESD protection diode array designed for USB Type-C™ and HDMI 2.0 circuit protection, rated for ESD strike dissipation to the highest level specified in IEC 61000-4-2 (17 kV contact discharge, 17 kV air gap discharge). The device's low dynamic resistance and low clamping voltage ensure further system-level protection against transient events. Additionally, the ESD122 is an ideal ESD solution for USB Type-C Tx/Rx lines. Since the USB Type-C connector has a two-layer structure, VIA is required when using quad-channel ESD devices, which reduces signal integrity. However, using four ESD122 (dual) devices minimizes the VIA count and simplifies board layout.
TLV9061IDPWR: The TLV9061, TLV9062, and TLV9064 are single, dual, and quad low-voltage operational amplifiers, respectively, with rail-to-rail input and output swing capability. These devices provide a cost-effective solution for low voltage, small size and high capacitive load drive applications. While the TLV906x capacitive loads are driven to 100 pF, the resistive open-loop output impedance makes it easier to stabilize with higher capacitive loads. As mentioned earlier, these op amps are designed for low voltage operation (1.8 V - 5.5 V) and have performance specifications similar to TI's TLVx316 and OPAx316 devices.

IWR1642: Based on Frequency Modulated Continuous Wave (FMCW) radar technology, this device is an integrated single-chip mmWave sensor capable of operating in the 76 to 81 GHz frequency band with up to 4 GHz continuous chirp. Manufactured on TI's low-power 45 nm RFCMOS process, the solution enables unmatched levels of integration in an ultra-small form factor. The IWR1642 is an ideal solution for low-power, self-monitoring, ultra-high-precision radar systems in industrial applications such as security surveillance, factory automation, material handling, traffic monitoring, building automation, and drones.
Today's industrial technology requires not only the most intelligent and advanced robotic systems, but also innovative simulation and embedded technologies. To support this need, TI offers a variety of solutions and reference designs that can speed or even simplify development efforts.
