INFINEON TLE7719

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
