7 / 33 page DocID7513 Rev 2 7/33 L6207 Pin connections 33 Package Name Type Function SO24/ PowerDIP24 PowerSO36 Pin no. Pin no. 6, 7, 18, 19 1, 18, 19, 36 GND GND Signal ground terminals. In PowerDIP and SO packages, these pins are also used for heat dissipation toward the PCB. 822 OUT1B Power output Bridge B output 1. 924 RCB RC pin RC network pin. A parallel RC network connected between this pin and ground sets the current controller OFF-time of the bridge B. 10 25 SENSEB Power supply Bridge B source pin. This pin must be connected to power ground through a sensing power resistor. 11 26 IN1B Logic input Bridge B input 1 12 27 IN2B Logic input Bridge B input 2 13 28 VREFB Analog input Bridge B current controller reference voltage. Do not leave this pin open or connect to GND. 14 29 ENB Logic input(1) Bridge B enable. LOW logic level switches OFF all Power MOSFETs of bridge B. This pin is also connected to the collector of the overcurrent and thermal protection transistor to implement overcurrent protection. If not used, it has to be connected to +5 V through a resistor. 15 30 VBOOT Supply voltage Bootstrap voltage needed for driving the upper Power MOSFETs of both bridge A and bridge B. 16 32 OUT2B Power output Bridge B output 2. 17 33 VSB Power supply Bridge B power supply voltage. It must be connected to the supply voltage together with pin VSA. 20 4 VSA Power supply Bridge A power supply voltage. It must be connected to the supply voltage together with pin VSB. 21 5 OUT2A Power output Bridge A output 2. 22 7 VCP Output Charge pump oscillator output. 23 8 ENA Logic input(1) Bridge A enable. LOW logic level switches OFF all Power MOSFETs of bridge A. This pin is also connected to the collector of the overcurrent and thermal protection transistor to implement overcurrent protection. If not used, it has to be connected to +5 V through a resistor. 24 9 VREFA Analog input Bridge A current controller reference voltage. Do not leave this pin open or connect to GND. 1. Also connected at the output drain of the overcurrent and thermal protection MOSFET. Therefore, it has to be driven putting in series a resistor with a value in the range of 2.2 K - 180 K, recommended 100 K Table 4. Pin description (continued) |
