5 / 31 page  L6728 Pin description and connection diagrams 5/31 2 Pin description and connection diagrams 2.1 Pin descriptions Figure 3. Pin connection (top view) Table 2. Pins description Pin # Name Function 1BOOT HS driver supply. Connect through a capacitor (100 nF) to the floating node (LS-Drain) pin and provide necessary bootstrap diode from VCC. 2 PHASE HS driver return path, current-reading and adaptive-dead-time monitor. Connect to the LS drain to sense RDS(on) drop to measure the output current. This pin is also used by the adaptive-dead-time control circuitry to monitor when HS MOSFET is OFF. 3 UGATE HS driver output. Connect directly to HS MOSFET gate. 4 LGATE / OC LGATE. LS driver output. Connect directly to LS MOSFET gate. OC. Over Current threshold set. During a short period of time following VCC rising over UVLO threshold, a 10 µA current is sourced from this pin. Connect to GND with an ROCSET resistor greater than 5 kΩ to program OC Threshold. The resulting voltage at this pin is sampled and held internally as the OC set point. Maximum programmable OC threshold is 0.55 V. A voltage greater than 0.6 V activates an internal clamp and causes OC threshold to be set at the maximum value. 5GND All internal references, logic and drivers are connected to this pin. Connect to the PCB ground plane. 6VCC Device and drivers power supply. Operative range from 5 V to 12 V. Filter with at least 1 nF MLCC to GND. 7 COMP / DIS COMP. Error amplifier output. Connect with an RF - CF // CP to FB to compensate the device control loop. DIS. The device can be disabled by pushing this pin lower than 0.75 V(typ). Setting free the pin, the device enables again. 8FB Error amplifier inverting input. Connect with a resistor RFB to the output regulated voltage. Output resistor divider may be used to regulate voltages higher than the reference. |
