The MC33990DR2 from NXP Semiconductors is an enhanced Class B serial transceiver designed for bi-directional, half-duplex communication. It meets the automotive SAE J-1850 Class B Data Communication Network Interface specification, making it suitable for on-board vehicle microcontrollers. This transceiver transmits and receives data on a single-wire bus at data rates up to 10.4 kbps using Variable Pulse Width Modulation (VPWM).
Key electrical features include operation directly from a vehicle's 12 V battery system, with a full operational bus dynamics range from 9.0 V to 16 V. It interfaces directly with standard 5.0 V CMOS microcontrollers. The device offers protection against shorts to battery and ground on the BUS pin, internal reverse battery protection, and a maximum VBAT capability of 40 V. It also incorporates thermal shutdown with hysteresis and voltage waveshaping for the bus output driver.
The MC33990DR2 is housed in an 8-pin SOIC package and is designed for surface mount applications. It operates within an ambient temperature range of -40°C to 125°C. The receiver hysteresis is specified at 200 mV.
