EVQ5862-LT-00A

The EVQ5862-LT-00A evaluation board is designed to demonstrate the capabilities of the MPQ5862-AEC1, a dual-channel, high-side (HS) power switch for a nominal 1.5A load per channel. The device covers a 5V to 16V input voltage (VINx, where x = A or B) range. The MPQ5862-AEC1 supports both a default internal current limit (2.4A) and a configurable, high-accuracy current limit via the I2C. This helps clamp the inrush current under short-circuit conditions, which improves system reliability. A selectable start-up slew rate also helps reduce the inrush current during start-up. In addition, fast-off functionality can quickly shut down the device if the channel current increases sharply. The MPQ5862-AEC1 communicates with the microcontroller unit (MCU) via the I2C interface. The device supports up to 6 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 can be obtained without additional external circuitry. The device integrates full diagnostics and protections, including input over-voltage protection (OVP) and under-voltage protection (UVP), output OVP for each channel, open-load and short-to-battery detection, over-current protection (OCP), short-circuit protection (fast-off), and over-temperature (OT) shutdown. Average and peak current detection improves diagnostic reliability in driver monitoring systems (DMS). The fault status can be reported via both the FT pin and the I2C. The MPQ5862-AEC1 is available in a TQFN-17 (3mmx4mm) package. It is available in AEC-Q100 Grade 1 and is compliant with AEC-Q100-012 Test Grade A.
