MC33291DWR2 Description

Short technical summary and product information.

The MC33291DWR2 from NXP Semiconductors is a versatile eight-output, low-side power switch designed for various applications, including automotive environments. It features an 8-bit serial peripheral interface (SPI) for direct control by a microcontroller, supporting protocols up to 3.0 MHz.

 

Key electrical specifications include a wide supply voltage range of 5.5 V to 26.5 V and individual output currents up to 500mA. The device incorporates robust fault protection mechanisms such as current limiting, open load detection, over-temperature, and over-voltage protection. It also features an internal 53 V clamp on each output for inductive switching protection.

 

Designed for ease of integration, the MC33291DWR2 is available in a 24-pin SOIC package suitable for surface mounting. Its low standby current and output-specific diagnostics enhance system reliability and efficiency. The operating temperature range is -40°C to 150°C (TJ).
