5.6 Timing Requirements
At VDD = 2V, 2.5% input overdrive(4) with
RPU = 10kΩ, VOH = 0.9 × VDD, and
VOL = 400mV, unless otherwise noted. RPU refers to the
pull-up resistor at the UV and OV pins.
| MIN | NOM | MAX | UNIT | ||
|---|---|---|---|---|---|
| tpd(HL) | High-to-low propagation delay(1) | 19 | µs | ||
| tpd(LH) | Low-to-high propagation delay(1) | 35 | µs | ||
| tR | Output rise time(2) | 2.2 | µs | ||
| tF | Output fall time(2) | 0.22 | µs | ||
| tSD | Startup delay(3) | 300 | µs | ||
(1) High-to-low and low-to-high refers to the transition at the SENSE pin
(2) Output transitions from 10% to 90% for rise times and 90% to 10% for fall times.
(3) During the power-on sequence, VDD must be at or above 2V for at
least tSD before the output is in the correct state.
(4) Overdrive = | (V(VDD) / VIT – 1) × 100% |.
