TIPGA460TPWRQ1

Overview

The PGA460TPWRQ1 is a highly integrated ultrasonic signal processor and transducer driver designed for automotive and industrial proximity sensing. It features an integrated driver for transformer-driven or direct-drive transducers and a dedicated DSP for echo envelope detection and distance calculation. The device includes a time-varying gain amplifier and 12-point thresholding to maintain high sensitivity across varying distances.

Why Choose This Part

This IC offers exceptional sensitivity with a programmable time-varying gain of 32 to 90 dB and dual 12-point threshold presets for complex echo environments. It simplifies system design by integrating the transducer driver, DSP for distance timers, and 42 bytes of EEPROM for configuration storage in a compact 16-TSSOP package. Diagnostics for decay frequency, excitation voltage, and supply monitoring ensure high system reliability in safety-critical applications.

Applications

Getting Started

Evaluation can be performed using the PGA460-Q1 EVM, which interfaces with a PC via a USB-to-UART/LIN bridge for rapid configuration. Developers should use the PGA460-Q1 GUI to tune the time-varying gain and threshold settings for their specific transducer and environment. Communication is established via USART, I2C, or a high-voltage One-Wire Interface (OWI) for flexible integration with host microcontrollers.
