10 / 15 page LB11922 No.7497-10/15 Continued from preceding page. Pin No. Pin name Function Equivalent circuit 19 20 FGIN- FGIN+ FG amplifier inputs. FGIN- : FG amplifier inverting input FGIN+ : FG amplifier noninverting input Insert capacitors between these pins (which have a potential of 1/2 VCC) and ground. 20 VCC 500 Ω 500 Ω 500 Ω 19 FGOUT 21 RFGND Output current detection. Connect a resistor between this pin and ground. VCC 21 22 RF Output current detection. Connect a resistor between this pin and ground. The output limitation maximum current, IOUT, is set to be 0.26/Rf by this resistor. VCC 22 23 GND Ground connection. 24 25 26 27 28 29 UL UH VL VH WL WH Outputs (that are used to drive external transistors). These are push-pull outputs. The PWM duty is controlled on the UH, VH, and WH side of these outputs. 24 26 28 25 27 29 VCC 30 VCC Power-supply voltage. Connect a capacitor between this pin and ground for power supply stabilization. 31 32 33 34 35 36 IN3- IN3+ IN2- IN2+ IN1- IN1+ Hall-effect device inputs. The input is seen as a high-level input when IN+ > IN-, and as a low-level input for the opposite state. If noise on the Hall-effect device signals is a problem, insert capacitors between the corresponding IN+ and IN- inputs. The logic high state indicates that VIN+ > VIN-. 36 34 32 VCC 500 Ω 500 Ω 31 33 35 14 17 NC These are unconnected pins, and can be used for wiring. |
