PIU
PGND (Pin 1/Pin 1):
Driver Ground. Connect the DRV
CC
bypass capacitor directly to this pin, as close as possible
to the IC. In addition, connect the PGND and SGND pins
together close to the IC, and then connect this node to the
source of the power MOSFET (or current sense resistor)
with as short and wide a PCB trace as possible.
BLANK (Pin 2
/NA
):
Current Sense Blanking Output. Use
this pin to assert a blanking time in the power MOSFET’s
source current sense signal. The LTC4441 pulls this
open-drain output to SGND if the driver output is low. The
output becomes high impedance after a programmable
blanking time from the driver leading edge output. This
blanking time can be adjusted with the RBLANK pin.*
RBLANK (Pin 3/NA):
Blanking Time Adjust Input. Connect
a resistor from this pin to SGND to set the blanking time.
A small resistor value gives a shorter delay. Leave this pin
floating if the BLANK pin is not used.*
SGND (Pin 4/Pin 2):
Signal Ground. Ground return for the
DRV
CC
regulator and low power circuitry.
IN (Pin 5/Pin 3):
Driver Logic Input. This is the non-
inverting driver input under normal operating conditions.
*Available only on the lo-lead version of the LTC4441.
EN/SHDN (Pin 6/Pin 4):
Enable/Shutdown Input. Pulling
this pin above 1.21V allows the driver to switch. Pulling
this pin below 1.09V forces the driver output to go
low. Pulling this pin below 0.45V forces the LTC4441/
LTC4441-1 into shutdown mode; the DRV
CC
regulator
turns off and the supply current drops below 12
μ
A.
FB (Pin 7/Pin 5):
DRV
CC
Regulator Feedback Input. Con-
nect this pin to the center tap of an external resistive
divider between DRV
CC
and SGND to program the DRV
CC
regulator output voltage. To ensure loop stability, use the
value of 330k
for the top resistor, R1.
V
IN
(Pin 8/Pin 6):
Main Supply Input. This pin powers the
DRV
CC
linear regulator. Bypass this pin to SGND with a 1
μ
F
ceramic, tantalum or other low ESR capacitor in close
proximity to the LTC4441/LTC4441-1.
DRV
CC
(Pin 9/Pin 7):
Linear Regulator Output. This output
pin powers the driver and the control circuitry. Bypass this
pin to PGND using a 10
μ
F ceramic, low ESR (X5R or X7R)
capacitor in close proximity to the LTC4441/LTC4441-1.
OUT (Pin 10/Pin 8):
Driver Output.
Exposed Pad (Pin 11/NA):
Ground. The Exposed Pad
must be soldered to the PCB ground.
