  • The L9637 is a monolithic integrated circuit containing standard ISO 9141 compatible interface functions.

    Key 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
