STMicroelectronics Drivers, Receivers, Transceivers L9637D013TR

The L9637D013TR is a monolithic integrated circuit designed for ISO 9141 compatible interface functions. It operates within a power supply voltage range of 4.5 V to 36 V, with transient protection up to 40 V. The device features reverse supply protection down to -24 V and has a low standby current consumption of 1 mA at VCC ,⧠0.5 V. This product includes a bidirectional K-I/O pin with a supply voltage-dependent input threshold and offers a typical output current limitation of 60 mA. It is equipped with integrated pull-up resistors for TX, RX, and LO, and provides defined output statuses in various conditions, including undervoltage and open input scenarios. The L9637D013TR is optimized for low electromagnetic interference (EMI) and includes an overtemperature shutdown function selective to the K-I/O pin. Engineers considering this product should note its high input impedance for open VS or GND connections and its defined output ON status for open LI or K inputs, making it suitable for applications requiring robust communication interfaces.
