Monolithic Power Systems

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.

Automotive-grade ideal diode controller.

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 SIP32433xEVB evaluation boards provide a convenient tool for evaluating the operation of the SIP32433A load switch, with latch off, and SIP32433B with auto retry. Operating from a supply-voltage range of 3 V to 23 V, the boards demonstrate the programmable current-limit range of the two devices, 150 mA to 3.5 A. 

The boards provide an input path current-sense resistor for current probing, and an onboard MOSFET for output short-circuit testing.
