Adjust VCC above the Startup threshold before setting to 15 V. 8. Low duty cycle pulse techniques are used during test to maintain junction temperature as close to ambient as possible. NCV3843BV: Tlow = −40°C, Thigh = +125°C. Guaranteed by design. NCV prefix is for automotive and other applications requiring site and change control. |
