BLDC Motor Pre-driver with Speed Control, Single-phase, 12 V, 24 V and 48 V LV8310H Overview The LV8310HGR2G is a pre-driver for a 12 V, 24 V and 48 V single www.onsemi.com phase BLDC motor, which controls motor rotational speed with the built-in closed loop speed controller. Its target speed can be set by input PWM duty cycle. The speed curve setting can be stored to the internal nonvolatile memory (NVM). In addition, Lead-angle can also 16 be adjusted by the configuration saved in the internal NVM. Thus, it can drive various kinds of motors at high efficiency and low noise. 1 TSSOP16 Features CASE 948F Driver Output for External Power FETs (P-MOS High Side, N-MOS Low Side) Selectable High Side Gate Driver Polarity: One for 12 V Motor MARKING DIAGRAM Voltage and the other for 24 V/48 V Motor Voltage with External 16 Level Shifter FET LV83 PI Closed Loop Speed Control Function 10H Single-phase Full Wave Driver ALYW PWM Duty Cycle Input (25 Hz to 100 kHz) 1 Soft Start-up Function PWM Soft Switching Phase Transitions A = Assembly Location L = Wafer Lot Soft PWM Duty Cycle Transitions (Changing the Target Speed Y = Year Gradually) W = Work Week Built-in Current Limit Function and Over Current Protection = PbFree Package Function (Note: Microdot may be in either location) Built-in Thermal Protection Function Built-in Locked Rotor Protection and Automatic Recovery Function FG or RD Signal Output Selectable ORDERING INFORMATION See detailed ordering and shipping information on page 34 of Dynamic Lead Angle Adjustment with Respect to Input Duty Cycle this data sheet.
