LTC4307
U U U PI FU CTIO S ENABLE (Pin 1):
Connection Enable Input. This is a 1.4V connection sequence described in the Operation section digital threshold input pin. For normal operation pull or tie has not been completed. READY also goes low when the ENABLE high. Driving ENABLE below 0.8V isolates SDAIN LTC4307 disconnects the inputs from the outputs due to from SDAOUT, SCLIN from SCLOUT and asserts READY the bus being stuck low for at least 30ms. READY goes high low. A rising edge on ENABLE after a fault has occurred when ENABLE is high and a connection is made. Connect forces a connection between SDAIN, SDAOUT and SCLIN, a pull-up resistor, typically 10k, from this pin to VCC to SCLOUT. Connect to VCC if unused. provide the pull-up. This pin can be fl oated if unused.
SCLOUT (Pin 2):
Serial Clock Output. Connect this pin to
SDAIN (Pin 6):
Serial Data Input. Connect this pin to an an SCL bus segment where stuck bus recovery is needed. SDA bus segment that needs to be isolated from stuck A pull-up resistor should be connected between this pin bus problems. A pull-up resistor should be connected and VCC. between this pin and VCC.
SCLIN (Pin 3):
Serial Clock Input. Connect this pin to an
SDAOUT (Pin 7):
Serial Data Output. Connect this pin SCL bus segment that needs to be isolated from stuck to the SDA bus segment where stuck bus recovery is bus problems. A pull-up resistor should be connected needed. A pull-up resistor should be connected between between this pin and VCC. this pin and VCC.
GND (Pin 4):
Device Ground. Connect this pin to a ground
VCC (Pin 8):
Supply Voltage Input. Place a bypass capacitor plane for best results. of at least 0.01μF close to VCC for best results.
READY (Pin 5):
Connection READY Status Output. The
Exposed Pad (Pin 9, DFN Package Only):
Exposed Pad READY pin is an open-drain N-channel MOSFET output that may be left open or connected to device ground. pulls low when ENABLE is low, or when the start-up and 4307f 6
