5 / 7 page LB1991V No.5792-5/7 Pin Function Pin No. Pin name Pin function Equivalent circuit 1 VCC1 Supply voltage for all circuits other than the IC internal output block and the amplitude control block. 2 VCC2 Supply voltage for the IC internal output control block and the amplitude control block. 3 VS Motor drive power supply. The voltage applied to this pin must not exceed VCC2. 5 UOUT U phase output. 7 VOUT V phase output. 9 WOUT W phase output. (These outputs include built-in spark killer diodes.) 6,8 RF Ground for the output power transistors. 3 5 6 (8) 2 (7,9) VCC2 VS RF 10k Ω 5k Ω 5k Ω 1/2 ×VS 1/4 ×VS Each OUT 10 VH+ 11 VH− Hall element bias voltage supply. A voltage that is typically 0.95V is generated between the VH+ and VH− pins (When IH is 5mA). 11 1 VCC1 VH− 10 VH+ 20k Ω About 1.9V About 0.9V 13 GND Ground for circuits other than the output transistor. The RF pin potential is the lowest output transistor potential. 14 FRC Forward/reverse selection. Applications can select motor forward or reverse direction rotation using this pin. (This pin has hysteresis characteristics.) 15 STBY Selects the bias supply for all circuits other than the FG comparators. The bias supply is cut when this pin is set to the low level. 14 VCC1 FRC 50k Ω 15 VCC1 STBY 100k Ω 16 17 UIN1 UIN2 U phase Hall element input. The logic high level is the state where the IN+ voltage is greater than the IN− voltage. 18 19 VIN1 VIN2 V phase Hall element input. The logic high level is the state where the IN+ voltage is greater than the IN− voltage. 20 21 WIN1 WIN2 W phase Hall element input. The logic high level is the state where the IN+ voltage is greater than the IN− voltage. 12 ANGLE Hall input/output gain control. The gain is controlled by the resistor connected between this pin and ground. 16 VCC1 4k Ω 17 400 Ω 400Ω 200 Ω 4k Ω 200 Ω (18,20) (19,21) 0.3V 1 17 VCC1 ANGLE 1.2V typ Each input of 1 Each input of 2 22 FGIN+ FG comparator non-inverting inputs. There is no internally applied bias. 23 FGIN− FG comparator inverting inputs. There is no internally applied bias. 24 FGOUT FG comparator outputs. There is an internal 20k Ω resistor load. 1 VCC1 24 200 Ω 23 200 Ω 22 FGIN− FGIN+ FGOUTN |
