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 C Type TLE 7719 Package P-TSSOP-28
