E-L9637D013TR Datasheet PDF - ST Microelectronics

●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
