Product Description

The EV65150/1DGT-00A is an evaluation board for MP65150/1DGT, single-channel, precision adjustable current-limited, power-distribution switch.

The EVB operates over a 2.5V to 5.5V range and provides a continuous output current of up to 1A. It offers programmable current limit between 60mA and 1.7A (typ) with ±10% accuracy by an external resistor. It is available with guaranteed current limits, making them ideal for load switching applications. When the output load exceeds the current-limit threshold or a short is present, the device limits the output current to a safe level by switching into a constant-current mode.

The FLAG(________) output will report a fail mode (low level) when over current or over temperature is encountered. The FLAG(________) will not change state when the input UVLO is triggered.

This device, available in 6-pin TQFN 2mmx2mm package, provides a very compact system solution with minimal reliance on external components.

The demo board default is for 1.19A current limit (RILIM=20k?).

IC Details

The MP6515 is an H-bridge motor driver. It operates from a supply voltage of up to 35V and delivers motor current up to 2.8A. Typically, the MP6515 is used to drive a DC brush motor. An internal current sensing circuit provides an output with voltage proportional to the load current. In addition, cycle-by-cycle current regulation/limiting is provided. These features do not require the use of a low-ohm shunt resistor. Internal safety features include over-current protection, input over-voltage protection, under-voltage lockout (UVLO), and thermal shutdown. The MP6515 is available in 16-pin 5.0mmx6.4mm TSSOP-EP and 3mmx4mm QFN package with exposed thermal pad.
