Shenzhen Meiyuxin Technology Co., Ltd. [NXP Agent] Supply Original MC33984CHFKR2 Power Switch IC - Power Distribution Dual 4mOhms smart! !

Product Description:

MC33984CHFKR2 is a dual self-protected 4.0 mOhm silicon switch used to replace electromechanical relays, fuses, and discrete devices in power management applications. The 33984 is designed for harsh environments, and it includes self-recovery features. The device is suitable for loads with high inrush current, as well as motors and all types of resistive and inductive loads. Programming, control, and diagnostics are implemented via the serial peripheral interface (SPI). A dedicated parallel input is available for alternate and pulse-width modulation (PWM) control of each output. SPI-programmable fault trip thresholds allow the device to be adjusted for optimal performance in the application.

MC33984CHFKR2 is packaged in a power-enhanced 12 mm x 12 mm nonleaded PQFN package with exposed tabs.

Features

• Dual 4.0 m max. high-side switch with parallel input or SPI control

• 6.0 V to 27 V operating voltage with standby currents < 5.0 A
