MP6650 Single-Phase, BLDC Motor Driver with Integrated Hall Sensor in a TSOT23-6 Package DESCRIPTION FEATURES Embedded Hall Sensor with High Sensitivity The MP6650 is a single-phase, brushless, DC Wide 3.3V to 18V Operating Input Range motor driver with integrated power MOSFETs and a Hall-effect sensor. The device drives Up to 2A Configurable Current Limit single-phase brushless DC fan motors with up Integrated Power MOSFETs: Total 740m to 2A of output current. The IC has a 3.3V to (HS-FET and LS-FET) 18V input voltage range and input line reverse- Configurable Speed Curve voltage protection (RVP) to save the external Built-In Adjustable Speed Curve Corner diode on the supply line. Setting Automatic Phase-Lock Detection of Winding The device controls the rotational speed BEMF and Current Zero-Crossing through the PWM signal on the PWM pin. It has Soft On/Off Phase Transition a rotational speed detection feature and rotor Rotational Speed Indicator (FG) Signal lock fault indication on the FG/RD pin with an 2kHz to 100kHz PWM Input Frequency open-drain output. The output speed vs. the Range input duty curve can be configured easily for Fixed 26kHz Output Switching Frequency flexible use. To reduce audible fan driver noise Input Line Reverse Voltage Protection (RVP) and power loss, the MP6650 features a soft Rotor Deadlock (RD) Protection on/off phase transition and an automatic phase- Thermal Protection and Automatic Recovery lock function of the motor winding BEMF and Built-In Input OVP, UVLO, and Automatic current. Recovery Available in TSOT23-6-L, TSOT23-6-R, Full protection features include input over- TSOT23-6-SL, and TSOT23-6-RSL voltage protection (OVP), under-voltage lockout Packages (UVLO), rotor deadlock (RD) protection, thermal shutdown, and input reverse protection. APPLICATIONS The MP6650 requires a minimal number of CPU Fan for Personal Computers or external components to save solution cost. It is Servers available in TSOT23-6-L, TSOT23-6-R, Brushless DC Motor TSOT23-6-SL, and TSOT23-6-RSL packages. All MPS parts are lead-free, halogen-free, and adhere to the RoHS directive.
