Specifications of ICB1FL03G

• Frequency: 20 ~ 100 kHz
• Current - Supply: 5mA
• Voltage - Supply: 8.4 V ~ 17 V
• Operating Temperature: -25°C ~ 125°C
• Package / Case: 20-SOIC (0.300", 7.50mm Width) 18 leads
• Lead Free Status / RoHS Status: Lead free / RoHS Compliant
• Current - Output: -
• Lead Free Status / Rohs Status: Details

The status failure mode is kept as long until a lamp removal is detected (interruption of current across filaments
and detection of the return of the current) or the supply voltage drops below UVLO. After a break down of the
supply voltage below the undervoltage lockout (UVLO) threshold the IC resets any failure latch and will try to
restart as soon as Vcc exceeds the start-up threshold.
An undervoltage (75%) of the bus voltage will not be latched as a fault condition. If the undervoltage lasts longer
than 80µs the Gate drives are switched off and the IC tries to restart after a Vcc hysteresis has been passed.
