L6918A (MASTER) PIN FUNCTION
N.
Name
Description
1
LGATE1
Channel 1 low side gate driver output.
2
VCCDR
LS Mosfet driver supply. 5V or 12V buses can be used.
3
PHASE1
This pin is connected to the Source of the upper mosfet and provides the return path for the
high side driver of channel 1.
4
UGATE1
Channel 1 high side gate driver output.
5
BOOT1
Channel 1 bootstrap capacitor pin. This pin supplies the high side driver. Connect through a
capacitor to the PHASE1 pin and through a diode to Vcc (cathode vs. boot).
6
VCC
Device supply voltage. The operative supply voltage is 12V.
7
GND
All the internal references are referred to this pin. Connect it to the PCB signal ground.
8
COMP
This pin is connected to the error amplifier output and is used to compensate the control
feedback loop.
9
FB
This pin is connected to the error amplifier inverting input and is used to compensate the
voltage control feedback loop.
A current proportional to the sum of the current sensed in both channel is sourced from this pin
(50
A at full load, 70A at the Over Current threshold). Connecting a resistor RFB between
this pin and VSEN pin allows programming the droop effect.
10
VPROG_OUT
Reference voltage output used for voltage regulation.
This pin must be connected together with the slave device VPROG_IN pin.
Filter to SGND with 1nF capacitor (a total 30nF distributed capacitance is allowed).
11
SYNC_OUT
Synchronization output signal. From this pin exits a square - 50% duty cycle - 5Vpp –90 deg
phase shifted wave clock signal that the Slave device PLL locks to.
Connect this pin to the Slave SYNC_IN pin.
12
SLAVE_OK
Open-drain input/output used for start-up and to manage protections as shown in the timing
diagram. Internally pulled-up. Connect together with other IC’s SLAVE_OK pin. Filter with 1nF
capacitor vs. SGND.
