MCZ33291LEG Description

Short technical summary and product information.

The MCZ33291LEG from NXP Semiconductors is an eight-output, low-side power switch designed for versatile applications, including automotive environments. It features an 8-bit serial peripheral interface (SPI) for direct control by microcontrollers, enabling management of inductive or incandescent loads.

 

Key electrical specifications include a supply voltage range of 4.5V to 5.5V and a load voltage range of 9V to 26.5V. Each output can deliver up to 500mA with a typical on-resistance of 1.1 Ohm. The device supports an SPI interface operating up to 3.0 MHz.

 

Innovative monitoring and protection features are integrated, such as very low standby current, SPI cascade fault reporting, internal 53V clamp on each output, output-specific diagnostics, and independent output shutdown. Fault protection includes current limiting, open load detection, over-temperature, and over-voltage protection. The operating temperature range is -40°C to 150°C (TJ).

 

The MCZ33291LEG is supplied in a 24-SOIC package suitable for surface mounting.
