... Circuit isolation also reduces the chance of tripping on system noise. A 90V open drain PWRGD pin provides status information and can be used to enable the DC/DC power supplies. HV110 is available in a thermally rugged DPAK-5 package that provides improved thermal resistance when compared to SO-8 based solutions Figure 1. Typical Application Circuit HV110 ...

... T Temperature Hysteresis HYS ( 1 ): HV110 will work in both Positive and Negative voltage applications, the maximum differential voltage between the UVLO Threshold to be modified using external resistors, when a zener diode is connected Shorted-circuit timer starts after POR timer Under-current timer starts when I ...

... MDIs is called a Midspan PSE. All the specifications for the PSE sitting in the End Point (e.g. the router) may not apply for the Midspan PSE. Even though HV110 device closely associated with the operation of PSE, in fact it is dependent on the PSE for its normal operation. ...

... PD Application IEEE Electrical & Timing Requirements Below are of the major features of HV110, some of which are usually found only in PSE devices. Provides an internal current limit for inrush, normal operation and overload conditions. Limits the input current to less than 10µA that will not interfere with Discovery from 2 ...

... PD application is well below 180uF so this feature is not of much significance application. Figure 7. HV110 turning 300uF Cport, still maintaining Figure 8. HV110 turning on into a 300uF Cport, the maximum input current of 400mA, does not need any still maintaining the maximum input current of 400mA ...

... The diode from base to PWRGD turns off classification as soon as PWRGD is pulled low to save power. The zener in series with the HV110 will keep the Classification components from drawing current until after Discovery. diode in series with the base of the bipolar transistor can block the maximum expected differential network voltage ...

... By using a PNP transistor, along with a low power zener and resistor instead, the built-in undervoltage thresholds can be utilized. Figure 10. Powering HV110 using a PNP transistor instead of a zener Figure 10 shows the modified circuit. Discovery stage, the input voltage is less than 10V. pin of the ...
