MC33811

• Product Introduction

MC33811Electromagnetic display integrated circuits

The 33811 is a 5-channel solenoid monitor IC used to verify correct electrical and mechanical electromagnetic operations. This IC includes five solenoid valve drive voltage monitoring stages and a serial peripheral interface (SPI) for communication and fault setup. This IC has the capability to analyze changes in the voltage distribution of the electromagnetic armature in the correct movement, crossing the solenoid driver MOSFET, which represents the actual solenoid current update. These features, along with cost-effective packaging, make the 33811 an ideal choice for powertrain solenoid monitoring applications. -------------------------------------------------- ------------------------------ Features-------------------------------------------------- ------------------------------ Typical operating voltage range: 10.5 VPWR > 15.5V interfaces, 3.3V and 5V microprocessors initialize all 5 fault outputs via SPI protocol reset pins, internal regulators, internal oscillators, unique electromagnetic current profile detection circuits, and the product is included in Freescale's long-term supply plan, guaranteeing supply at least 15 years after launch
