Notes
20.
V2 specification with external capacitor. Stability requirement: capacitance > 42
F and ESR < 1.3 (tantalum capacitor), external
resistor between base and emitter required. Measurement conditions: ballast transistor MJD32C, capacitance > 10
F tantalum, 2.2 k
resistor between base and emitter of ballast transistor.
21.
The guaranteed V2CTRL current capability is 10 mA. No active current limiting is used so the actual available current may be higher.
22.
Push-pull structure with tri-state condition (CS HIGH).
23.
Output pin only. Supply from VDD. Structure switch to ground with pull-up current source.
Table 5. Static Electrical Characteristics (continued)
Characteristics noted under conditions 4.75 V
V2 5.25 V, 5.5 V VSUP 18 V, and -40 C TA 125 C. Typical values
noted reflect the approximate parameter mean at TA = 25 C under nominal conditions, unless otherwise noted.
