MC33291DW Description

Short technical summary and product information.

The MC33291DW from NXP Semiconductors is a versatile eight-output, low-side power switch featuring an 8-bit serial input control via SPI. This device integrates SMARTMOS technology, combining CMOS logic, bipolar/MOS analog circuitry, and DMOS power MOSFETs.

 

Key electrical specifications include a wide supply voltage range of 5.5 V to 26.5 V, with a typical operating range of 9.0 V to 16 V. It offers 1.0 A peak current outputs with a maximum RDS(ON) of 1.6 Ω at 150°C TJ, and a typical RDS(ON) of 550 mΩ. The outputs are current-limited to handle in-rush currents and feature internal 53 V clamps for inductive switching protection.

 

Innovative monitoring and protection features include very low standby current (25 μA maximum sleep current), SPI cascade fault reporting, output-specific diagnostics, and independent output shutdown. The device operates over an ambient temperature range of -40°C to 125°C.

 

Packaged in a 24-pin SOICW, the MC33291DW is designed for surface mount applications. It interfaces directly with microcontrollers, making it suitable for controlling various inductive or incandescent loads in automotive and other demanding environments.
