SI9182DH - AD - T1 SI9182DH - AD - T1 SI9182DHADT1 Price The inductor is selected that would resonate with the total capacitance at the LO frequency using the following equation 1 L = ---------------- - 1.3nH where C=1.6pF C (2*pi*F)2 To fine tune the LO, two methods have been proven to work well: SI9182DH - AD - T1 SI9182DH - AD - T1 SI9182DHADT1 on stock The PW-8X075P6 0utputs are completely short-circuit-protected from either a hard or soft short (required PW-84075 and some external circuit) to the VBUS+ or VBUS- lines. Each output tran- sistor is individually short-circuit (hard) protected by circuitry that detects the desaturation voltage for that transistor during a short condition. Once a hard short circuit condition is detected, the active output transistors are shutdown. If the AUTO RESET is tied to SC FAULT, the circuit will auto reset, remove the short cir- cuit flag, and reactivate the output transistor within 40 t0 100ms. | / / - -- / _ ' / | -- \.\ \ \ 0.4 mA \ I \ !ICURRENT= | | - '- ' --l | 'uunnci ' = , l,- ,'UURRRFENT = 2 - / / JRRENT = // / | | | | | N | | | Q CURRENT = 0.2 mA | | |
