MAX6650EUB+

Maxim Integrated · Motor Driver ICs · MSOP-10

MAX6650EUB+ from Maxim Integrated, in a MSOP-10. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 TACH0 input Tachometer input used to close the loop around the fan tachometer, with input impedance of 70 kΩ to 150 kΩ specified for 0 < VTACH < 9V.
2 GND power_in Ground reference for the device.
3 SDA bidirectional 2-wire serial-data input/output, open drain, for the SMBus/I2C-compatible interface.
4 SCL input 2-wire serial clock input for the SMBus/I2C-compatible interface.
5 ADD input Slave address select input; pin-strapping to GND, VCC, high-Z or 10kΩ to GND selects one of four slave addresses per Table 1.
6 GPIO1 bidirectional General-purpose input/output, open drain, configurable as a FULL ON output or as a general-purpose input, with 10 mA sink capability.
7 GPIO0 bidirectional General-purpose input/output, open drain, configurable as a general input/output or an active-low ALERT output, with 10 mA sink capability.
8 OUT output Output that drives the external MOSFET or bipolar transistor gate or base to regulate the voltage across the fan.
9 VCC power_in Power supply input, +3.0V to +5.5V.
10 FB input Feedback input that closes the loop around the external MOSFET or bipolar transistor; FB is rated to +13.2V maximum.
