Airbag Satellite Receive IC (SatRIC)

TLE 7719

Overview

Features

• Receiver for current modulated data from 4 satellite

channels

• Max. data rate 125 kBaud

• Decoding of 2 Manchester Protocols, programmable

data length (up to 16 bit)

• Channel configuration in pairs (Data length, Code

Type)

• Programmable sample clock generator with two clock options: internal system clock

(1 MHz) or external clock line (up to 2 MHz)

• Supply of satellite channels via 4 independent +10.0 V voltage regulators

• Asynchronous and synchronous (automatic sync pulse generation) data transmission

modes

• Logic operating voltage 5.0 V

• 2 Digital outputs for voltage-converted received satellite signals

• 16-bit - SPI Interface with Daisy chain capability

• Burst Read function allows fast readout of all four received satellite data

• Constant current threshold level over wide range of satellite quiescent current

• Current limitation to prevent device destruction in case of satellite output shorted to

ground

• Leakage detection to GND or Supply Voltage; low line current detection

• Over-temperature shutdown for all channels

• Analogue output buffer for measurements via analog input of a

µC
