Note 1: Specifications guaranteed for the stated global conditions. 100% production tested at TA = +25°C and TA = +85°C.
Specifications at TA = -40°C to +85°C are guaranteed by design. These devices meet the parameters specified when at
least one of IN1/IN2/IN3 is between 2.7V to 5.5V, while the remaining IN1/IN2/IN3 are between 0 and 5.5V.
Note 2: A current ID = 2.5A ±15% is generated internally and is used to set the DELAY and TIMEOUT periods and used as a refer-
ence for tDELAY and tTIMEOUT.
Note 3: The total DELAY is tDELAY = 200s + (500k x CDELAY). Leave DELAY unconnected for 200s delay. The total TIMEOUT is
tTIMEOUT = 200s + (500k x CTIMEOUT). Leave TIMEOUT unconnected for 200s timeout.
Note 4: A current IS = 25A ±10% is generated internally and used as a reference for tFAULT, tRETRY, and slew rate.
Note 5: During power-up, only the condition OUT_ < ramp - VTRK is checked in order to stop the ramp. However, both conditions
OUT_ < ramp – VTRK_F and OUT_ > ramp + VTRK_F cause a fault. During power-down, only the condition OUT > ramp +
VTRK is checked in order to stop the ramp. However, both conditions OUT_ < ramp - VTRK_F and OUT_ > ramp + VTRK_F
cause a fault (see Figure 10). Therefore, if OUT1, OUT2, and OUT3 (during power-up tracking and power-down) differ by
more than 2 x VTRK_F, a fault condition is asserted.
Note 6: A 100 pulldown to GND activated by a fault condition. See the Internal Pulldown section.
ELECTRICAL CHARACTERISTICS (continued)
(IN1, IN2, or IN3 = +2.7V to +5.5V, EN/UV = MARGIN = ABP, TA = -40°C to +85°C, unless otherwise specified. Typical values are
at TA = +25°C, unless otherwise noted.) (Note 1)
