To select the latch-off mode, ROTM should be greater than 150 kΩ and tOTM is given by ROTM × (1.0 × 10 -11). To select the shutdown/retry mode, R OTM should be less than 100 k Ω and tOTM is given by ROTM × (5.0 × 10 -11). (4) Thermal shutdown occurs at temperatures higher than the normal operating range. Device performance at or near thermal shutdown temperature is not specified or assured.
