AMBIENT TEMPERATURE IN °C

Dwg. GH-054A

NOTE – Permitted duty cycle will be less than 100%

at maximum ambient temperature with high supply

voltages, i.e., TA ≥ 140°C, VCC ≥ 12 V, and the “LT”

package. The thermal shutdown circuitry does not

protect the device from these stresses (see Internal

Protective Features).
