NXP Semiconductors PMIC - Power Distribution Switches, Load Drivers MC33291DW

The MC33291DW is an eight-output, low-side power switch designed for automotive applications but suitable for various environments. It features an 8-bit serial input control via SPI, allowing for direct interfacing with microcontrollers. The device operates over a wide supply voltage range of 5.5 V to 26.5 V and can handle peak output currents of 1.0 A with a maximum R_DS(ON) of 1.6 Oc at 150¬8C. Key protection features include output-specific diagnostics, independent shutdown capabilities, and a 53 V clamp on each output during inductive switching. The device also boasts low standby current of 25 OºA and operational current of 4.0 mA. It is specified for an ambient temperature range of -40¬8C to 125¬8C, making it suitable for demanding applications. The MC33291DW is available in a 24-pin SOICW package and is Pb-free, indicated by the suffix code EG.
