Adjust VCC above the startup threshold before setting to 12 V. Low duty cycle pulse techniques are used during test to maintain junction temperature as close to ambient as possible. 15. Once a fault detection activated it, the Disabling Block Latch gets reset when the VCC becomes lower than this threshold. 16. Refer to Note 14. 17. This consumption is measured while the circuit is inhibited by the Definitive Latch. |
