NXP Semiconductors PMIC - Power Management - Specialized MCZ33800EK

The MCZ33800EK is a power management integrated circuit designed for engine control applications. It features two programmable constant current drivers, an octal low-side serial switch, and six external MOSFET gate pre-drivers. The device operates within a voltage range of 5V to 36V and interfaces with 3.3V and 5V microprocessors via SPI protocol. Key protective features include over-voltage, under-voltage, thermal protection, and comprehensive fault detection mechanisms. Additional functionalities include a low power sleep mode with a standby current of approximately 10µA, diagnostics for heated exhaust gas oxygen sensors, and the ability to control outputs through both serial and parallel inputs. The MCZ33800EK supports PWM control with programmable frequency and duty cycle, making it suitable for various powertrain applications. The device is packaged in a 54-pin SOICW EP format and is Pb-free, indicated by the EK suffix.
