TLE8262E
HERMES Overview
HS CAN Transceiver
⢠Compliant to ISO 11898-2 and 11898-5 as well as SAE J2284
⢠CAN data transmission rate up to 1 MBaud
⢠Supplied by dedicated input VccHSCAN
⢠Low power mode management
⢠Bus wake-up capability via CAN message
⢠Excellent EMC performance (very high immunity and very low emission)
⢠Bus pins are short circuit proof to ground and battery voltage
⢠8 kV ESD gun test on CANH / CANL / SPLIT
⢠Bus failure detection
LIN Transceiver
⢠LIN2.1 conformance, LIN2.1 is back compatible to LIN1.3 and LIN2.0
⢠SAE J2602-2 conformance
⢠Compatible to ISO 9141 (K-L-Line)
⢠Transmission rate up to 20 kBaud, LIN Flash Mode 115kBaud
⢠8 kV ESD gun test on Bus pins
Voltage Regulators
⢠Low-dropout voltage regulator
⢠Vcc1µC, 200 mA, 5 V ±2% for external devices, such as microcontroller and RF receiver
⢠Vcc2, 200 mA, 5 V ±2% for external devices or the internal HS CAN cell
⢠Vcc3, current limitation by shunt resistor (up to 400 mA with 220 m⦠shunt resistor), 5 V ±4% with external PNP
transistor; for example: to supply additional external CAN transceivers
⢠Vcc1µC, undervoltage Time-out
Supervision
⢠Reset output with integrated pull-up resistor
⢠Time-out or Window Watchdog, SPI configured
⢠Watchdog Timer from 16 ms to 1024 ms
⢠Check sum bit for Watchdog configuration
⢠Reset due to Watchdog failure can be inhibited with Test pin (SBC SW Development Mode)
Interrupt Management
⢠Complete enabling / disabling of interrupt sources
⢠Timing filter mechanism to avoid multiple / infinite Interrupt signals
Limp Home
⢠Open drain Limp Home outputs
⢠Dedicated internal logic supply
⢠Maximum safety architecture for Safety Operation Mode
⢠Configurable Fail-Safe behavior
