Measure the value at which FLT is asserted VIN + 0.6 VIN + 0.8 VIN + 1 V VHYS(OVP) Hysteresis on OVP VD+/VD– Difference between rising and falling OVP thresholds on VD+/VD- 50 mV VOVP(FALLING) Input overvoltage protection threshold VD+/VD– Decrease VD+ or VD- (with D+ or D-) from 4.5 V to 2 V. Measure the value at FLT is deasserted VIN + 0.525 VIN + 0.75 VIN + 0.975 V SHORT TO BATTERY V(VBUS_STB) VBUS hotplug short-to-battery tolerance VBUS_CON Charge battery-equivalent capacitor to test voltage then discharge to pin under test through a 1 meter, 18ga wire. (See the STB Test Setup diagram for more details) 18 V V(DATA_STB) Data line hotplug short-to- battery tolerance VD+/VD- 18 V DATA LINE SWITCHES – VD+ to D+ or VD- to D- CON Equivalent On Capacitance Capacitance of D+/D- switches when enabled - measure on connector side across bias voltage 6.2 pF RON On Resistance Measure resistance between D+ and VD+ or D- and VD-, voltage between 0 and 0.4 V 4 6.5 Ω RON(Flat) On Resistance flatness Measure resistance between D+ and VD+ or D- and VD-, sweep voltage between 0 and 0.4 V 0.2 1 Ω BWON On Bandwidth (–3dB) Measure S21 bandwidth from D+ to VD+ or D- to VD- with voltage swing = 400 mVpp, VCM= 0.2 V 860 MHz BWON_DIFF On Bandwidth (–3dB) Measure SDD21 bandwidth from D+ to VD+ and D- to VD- with voltage swing = 800 mVpp differential, VCM= 0.2 V 1050 MHz Xtalk Crosstalk Measure S21 bandwidth from D+ to VD- or D- to VD+ with voltage swing = 400mVpp. Be sure to terminate open sides to 50 ohms. f = 480 MHz -34 dB nFET SWITCH - Vbus R(DISCHARGE) Output discharge resistance EN = 5 V, Set VBUS_CON = 5 V and measure current flow to ground 12500 Ω RDS_ON Switch ON resistance VBUS_CON = 5 V, IOUT = 0.5 A 63 150 m Ω |
