Product overview
Description
The L9637 is a monolithic integrated circuit containing standard ISO 9141 compatible interface functions.-
All features
- Defined OFF output status in undervoltage condition and VS or GND interruption
- K output current limitation, typ. IK = 60 mA
- High input impedance for open VS or GND connection
- Controlled output slope for low EMI
- Defined K output OFF for TX input open
- Defined output ON status of LO or RX for open LI or K inputs
- EMI robustness optimized
- Integrated pull up resistors for TX, RX and LO
- Overtemperature shut down function Selective to K-I/O pin
- Bidirectional K-I/O pin with supply voltage dependent input threshold
- Operating power supply voltage range 4.5 V ≤ VS ≤ 36 V (40 V for transients)
- Standby mode with very low current consumption ISSB ≤ 1 mA @ VCC ≤ 0.5 V
- Reverse supply (battery) protected down to VS ≥ -24 V
- TTL compatible TX input
- Wide input and output voltage range -24 V ≤ VK ≤ VS
- Low quiescent current in off condition ISOFF = 120 µA
