The MC33298P from NXP Semiconductors is a versatile, smart eight-output low-side power switch. It utilizes an 8-bit serial-in shift register to control an 8-bit parallel output latch, enabling independent control of eight ON/OFF output switches. This device is designed to interface directly with microcontrollers for controlling various inductive or incandescent loads such as solenoids, relays, lamps, and small DC motors.
Key electrical specifications include a wide supply voltage range of 5.5 to 26.5V and peak output currents of up to 1A. The outputs feature low ON-resistance (0.4Ω typical at 25°C) and can sink up to 3.0A of transient current. Continuous current handling is 0.5A per output when all outputs are simultaneously ON and the device is soldered to a typical PC board. The interface is SPI, supporting data rates up to 3.0MHz. Protection features include current limiting, open load detection, over-temperature, and over-voltage protection.
The MC33298P is available in a 20-DIP (0.300", 7.62mm) through-hole package. It operates over a wide temperature range of -40°C to 150°C (TJ). The device also features very low standby current (25µA maximum) and operational current (4.0mA maximum).
Applications include automotive systems, industrial controls, and general-purpose power switching where precise control and protection of moderate current loads are required.
