Single Channel 60mA to 1.7A Programmable Current-Limited Power Distribution Switches EV Board
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=20kΩ).

5.4V - 35V,2.8A,H-Bridge Motor Driver in TSSOP16-EP and QFN3X4-20
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. For the MP6515, control of the outputs is accomplished through the PHASE, ENBL, BRAKE, and BMODE pins.
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.
