OCH2980 Two Phase Hall-Effect Smart Fan Motor Controller ◼ General Description The OCH2980 is a single-chip solution for driving two-coil brushless direct current (BLDC) fans and motors. The device includes a Hall-effect sensor, dynamic offset correction and two complementary open-drain output drivers with internal Zener diode protection. It is optimized for low start-up voltage. To help protect the motor coils, the OCH2980 provides Rotor Lock Protection which shuts down output drives if rotor lock is detected. The device automatically re-starts when the rotor lock is removed. Over temperature shutdown provides thermal protection for the device. The OCH2980 is available in SIP4 package. ◼ Features ⚫ Single-Chip solution ⚫ High sensitivity Hall-effect Sensor ⚫ Operating Voltage: 3.
