Pins descriptions 1 2 3 4 LGATE GND PHASE UGATE VCC EN PWM BOOT 5 6 7 8 L6743D Pin # Name Function 1BOOT high-side driver supply. This pin supplies the high-side floating driver. Connect through a RBOOT - CBOOT capacitor to the PHASE pin. Internally connected to the cathode of the integrated bootstrap diode. See Section 4.3 for guidance in designing the capacitor value. 2PWM Control input for the driver, 5 V compatible. This pin controls the state of the driver and which external MOSFET have to be turned-ON according to EN status. If left floating and in conjunction with EN asserted, it causes the driver to enter the High-Impedance (HiZ) state which causes all MOSFETs to be OFF. See Section 4.1 for details about HiZ. 3EN Enable input for the driver. Internally pulled low by 15 k Ω. Pull high to enable the driver according to the PWM status. If pulled low will cause the drive to enter HiZ state with all MOSFET OFF regardless of the PWM status. See Section 4.1 for details about HiZ. 4VCC Device and LS driver power supply. Connect to any voltage between 5 V and 12 V. Bypass with low-ESR MLCC capacitor to GND. 5LGATE low-side driver output. Connect directly to the low-side MOSFET gate. A small series resistor can be useful to reduce dissipated power especially in high frequency applications. 6GND All internal references, logic and drivers are referenced to this pin. Connect to the PCB ground plane. 7 PHASE high-side driver return path. Connect to the high-side MOSFET source. This pin is also monitored for the adaptive dead-time management and Pre-OV Protection. 8UGATE high-side driver output. Connect to high-side MOSFET gate. |
