MP6550 Single Brushed DC Motor Driver Carrier

DESCRIPTION

The MP6550 from Monolithic Power Systems (MPS) is an H-bridge motor driver IC that can be used for bidirectional control of one brushed DC motor at 1.8 V to 22 V. It can supply up to about 1.7 A continuously and features configurable current sensing and current limiting. Since this board is a carrier for the MP6550, we recommend careful reading of the MP6550 datasheet (714k pdf). The board ships populated with all of its SMD components, including the MP6550.

FEATURES

• H-bridge motor driver: can drive one DC motor
• Motor supply voltage: 1.8 V to 22 V
• Logic supply voltage: 1.8 V to 5 V
• Output current: up to 1.7 A continuous; operation at low motor and logic supply voltages reduces the maximum continuous output current
• Current control limits peak current to 2.5 A by default (this limit can be adjusted)
• Under-voltage lockout and protection against over-current and over-temperature
• Carrier board adds reverse-voltage protection up to 20 V
• Compact size (0.5″×0.6″)
