EVQ77240FS-LT-00A 16V, 0.8A,180mΩ RDS(ON), Quad-Channel, High-Side Load Switch Evaluation Board, AEC-Q100 Qualified
The EVQ77240FS-LT-00A evaluation board is designed to demonstrate the capabilities of the MPQ77240FS-AEC1, a quad-channel, high-side power switch for a nominal 0.8A load per channel. The device covers a 5V to 16V input voltage (VINA/B) range.
The MPQ77240FS-AEC1 supports an internal current limit and a configurable, high-accuracy current limit via the I2C. This helps to clamp the inrush current under short-circuit conditions, which improves system reliability. A selectable start-up slew rate also helps to reduce the inrush current during start-up. In addition, a fast-off function can quickly turn off the device if the channel current increases sharply.
The MPQ77240FS-AEC1 communicates to the microcontroller (MCU) via the I2C interface. The device supports up to six addresses, set via an external resistor.
With the help of an internal analog-to-digital converter (ADC), the channel currents, supply voltages, reference voltage (VREF), and output voltages (VOUT) can be obtained without additional external circuitry. Full diagnostics and protections are developed for the device, including input over-voltage (OV) and under-voltage (UV) detection, output OV for each channel, open-load and short-to-battery detection, over-current protection (OCP), fast-off short-circuit protection (SCP), and over-temperature (OT) shutdown. Average and peak current detection improves diagnostic reliability in driver monitoring systems (DMS). Fault statuses can be reported via both the FT pin and I2C interface.
The MPQ77240FS-AEC1 is available in a TQFN-17 (3mmx4mm) package. It is available in AECQ100 Grade 1 and compliant with AEC-Q100-012 Test Grade A.
