7 / 24 page  L6230 Pin connection Doc ID 18094 Rev 2 7/24 Table 5. Pin description Pin Type Function VBOOT Power supply Bootstrap voltage needed for driving the upper power MOSFETs. VCP Output Charge pump oscillator output. DIAG-EN Logic output/input Double function: chip Enable as input and Overcurrent/Over-temperature indication as output. LOW logic level switches OFF all Power MOSFETs, putting the power stages in high impedance status. An internal open drain transistor pulls to GND the pin when an overcurrent on one of the High Side MOSFETs is detected or during Thermal Protection. IN1 Logic input Logic input half bridge 1. EN1 Logic input Enable input half bridge 1. IN2 Logic input Logic input half bridge 2. EN2 Logic input Enable input half bridge 2. IN3 Logic input Logic input half bridge 3. EN3 Logic input Enable input half bridge 3. CP- Analog input Inverting input of internal comparator. CP+ Analog input Non-Inverting input of internal comparator. CPOUT Output Open-drain output of internal comparator. SENSE3 Half bridge 3 source pin. This pin must be connected to power ground through a sensing power resistor. OUT3 Power output Output half bridge 3. VSB Power supply Half bridge 3 power supply voltage. it must be connected to the supply voltage together with pin VSA. SENSE2 Half bridge 2 source pin. This pin must be connected to power ground through a sensing power resistor. OUT2 Power output Output half bridge 2. SENSE1 Half bridge 1 source pin. This pin must be connected to power ground through a sensing power resistor. OUT1 Power output Output half bridge 1. VSA Power supply Half bridge 1 and half bridge 2 power supply voltage. It must be connected to the supply voltage together with pin VSB. GND Ground Ground terminal. |
