6 / 29 page Pin connection L6226Q 6/29 Doc ID 14335 Rev 5 Table 4. Pin description N° Pin Type Function 1, 21 GND GND Signal ground terminals. 9 OUT1B Power output Bridge B output 1. 11 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. 12 SENSEB Power supply Bridge B source pin. This pin must be connected to power ground directly or through a sensing power resistor. 13 IN1B Logic input Bridge B input 1 14 IN2B Logic input Bridge B input 2 15 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. 16 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. 17 VBOOT Supply voltage Bootstrap voltage needed for driving the upper power MOSFETs of both bridge A and bridge B. 19 OUT2B Power output Bridge B output 2. 20 VSB Power supply Bridge B power supply voltage. It must be connected to the supply voltage together with pin VSA. 22 VSA Power supply Bridge A power supply voltage. It must be connected to the supply voltage together with pin VSB. 23 OUT2A Power output Bridge A output 2. 24 VCP Output Charge pump oscillator output. 25 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. 26 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. 27 IN1A Logic input Bridge A logic input 1. 28 IN2A Logic input Bridge A logic input 2. 29 SENSEA Power supply Bridge A source pin. This pin must be connected to power ground directly or through a sensing power resistor. 30 OCDA Open drain output Bridge A overcurrent detection and thermal protection pin. An internal open drain transistor pulls to GND when overcurrent on bridge A is detected or in case of thermal protection. 31 OUT1A Power output Bridge A output 1. |
