7 / 29 page ![]() DocID07617 Rev 4 7/29 L6206 Pin connections 29 Package Name Type Function SO24 PowerSO36 Pin no. Pin no. 924 OCDB Open drain output Bridge B overcurrent detection and thermal protection pin. An internal open drain transistor pulls to GND when overcurrent on bridge B is detected or in case of thermal protection. 10 25 SENSEB Power supply Bridge B source pin. This pin must be connected to power ground directly or 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 PROGCLB R pin Bridge B overcurrent level programming. A resistor connected between this pin and ground sets the programmable current limiting value for the bridge B. By connecting this pin to ground the maximum current is set. This pin cannot be left non-connected. 14 29 ENB Logic input Bridge B Enable. LOW logic level switches OFF all power MOSFETs of Bridge B. If not used, it has to be connected to +5 V. 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 Bridge A enable. LOW logic level switches OFF all power MOSFETs of bridge A. If not used, it has to be connected to +5 V. 24 9 PROGCLA R pin Bridge A overcurrent level programming. A resistor connected between this pin and ground sets the programmable current limiting value for the bridge A. By connecting this pin to ground the maximum current is set. This pin cannot be left non-connected. Table 4. Pin description (continued) |
