The EVM3804-G-00A provides a ready-made hardware platform for evaluating the MPM3804 step-down switch-mode converter module. 

The module, supplied in a surface-mount 2 mm x 2 mm QFN package, supplies a maximum continuous output current of 0.6 A from an input voltage ranging between 2.3 V and 5.5 V, with excellent load and line regulation. 

The output voltage can be regulated as low as 0.6V. Only input, output capacitors and feedback resistors are needed to complete the design.

The Monolithic Power Systems EVQ5850-J-00A evaluation board demonstrates the capabilities of the MPQ5850, a 36 V smart diode controller with reverse protection.

The MPQ5850 diode controller can drive an external N-channel MOSFET to replace a Schottky diode for reverse input protection. The 20 mV ultra-low dropout minimizes power loss and enables a low minimum input voltage, which makes the MPQ5850 well-suited to cold-crank conditions in automotive applications. 

The 4 μA shutdown current also makes the MPQ5850 ideal for battery-powered applications. The ultra-fast transient response meets the requirements of the ISO16750 standard.

The EVQ5850-J-00A board is fully assembled and tested.

The EVQ6615-QK-00A is an H-bridge dc motor driver evaluation board featuring the MPQ6615-AEC1 IC, which operates from an input voltage of up to 40 V. 

The H-bridge consists of four N-channel power MOSFETs. An internal charge pump generates the gate driver supply voltages for the high-side MOSFETs, and a trickle charge circuit maintains sufficient gate driver voltages for 100% duty cycle operation.

The current flowing through the two Sx outputs is sensed via the internal current-sensing circuits. Each phase has an Output pin which sources or sinks a current proportional to each phase’s output current. Only the current flowing through the low-side MOSFET is sensed. This current is sensed in both the forward and reverse directions.

Internal safety features include over-current protection, under-voltage lockout protection, and thermal shutdown. The input control signals for the MPQ6615-AEC1 are applied through the connector on the board.

The MPQ6615-AEC1 can be used to drive brushed dc motors, door lock and latch motors, and seat actuators.

The EVM54304-MN-01A is an evaluation board designed to demonstrate the capabilities of the MPM54304, a four-channel output power module with an I2C interface. Channels 1 and 2 can deliver up to 3A (or a shared 6A) of continuous output current. Channels 3 and 4 can deliver up to 2A (or a shared 4A) of continuous output current.
