Features for the PGA460

  • Fully integrated solution for ultrasonic sensing
  • Complimentary low-side drivers with configurable current limit supporting both transformer based and direct drive topology for transducer excitation
  • Single transducer for both burst/listen or a transducer pair, one for burst and the other for listen operation
  • Low-noise receiver with programmable 6-point time-varying gain (32 to 90 dB) with DSP (BPF, demodulation) for echo envelope detection
  • Two presets of 12-point time-varying threshold for object detection
  • Timers to measure multiple echo distance and duration
  • Integrated temperature sensor
  • Record time for object detection up to 11 m
  • 128 bytes of RAM for echo recording
  • 42 bytes of user EEPROM to store configuration for fast initialization
  • One-wire high-voltage time-command interface or USART asynchronous interface
  • CMOS level USART interface
  • Sensor diagnostics (decay frequency and time, excitation voltage), supply, and transceiver diagnostics

Description for the PGA460

The PGA460 device is a highly-integrated system on-chip ultrasonic transducer driver and signal conditioner with an advanced DSP core. The device has a complimentary low-side driver pair that can drive a transducer either in a transformer based topology using a step-up transformer or in a direct-drive topology using external high-side FETs. The device can receive and condition the reflected echo signal for reliable object detection. This feature is accomplished using an analog front-end (AFE) consisting of a low-noise amplifier followed by a programmable time-varying gain stage feeding into an ADC. The digitized signal is processed in the DSP core for both near-field and far-field object detection using time-varying thresholds.

The main communication with an external controller is achieved by either a time-command interface (TCI) or a one-wire USART asynchronous interface on the IO pin, or a CMOS-level USART interface on the RXD and TXD pins. The PGA460 can be put in ultra-low quiescent current low-power mode to reduce power consumption when not in use and can be woken up by commands on the communication interfaces.

The PGA460 also includes on-chip system diagnostics which monitor transducer voltage during burst, frequency and decay time of transducer to provide information about the integrity of the excitation as well as supply-side and transceiver-side diagnostics for overvoltage, undervoltage, overcurrent and short-circuit scenarios.

Carrier options

You can choose different carrier options based on the quantity of parts, including full reel, custom reel, cut tape, tube or tray.

A custom reel is a continuous length of cut tape from one reel to maintain lot- and date-code traceability, built to the exact quantity requested. Following industry standards, a brass shim connects an 18-inch leader and trailer on both sides of the cut tape for direct feeding into automated assembly machines. TI includes a reeling fee for custom reel orders.

Cut tape is a length of tape cut from a reel. TI may fulfill orders using multiple strips of cut tapes or boxes to satisfy the quantity requested.

TI often ships tube or tray devices inside a box or in the tube or tray, depending on inventory availability. We pack all tapes, tubes or sample boxes according to internal electrostatic discharge and moisture-sensitivity-level protection requirements.
