TA = TJ = -40°C to +125°C, unless otherwise noted. Typical values are at TA = +25°C. All voltages are referenced to PGND, unless otherwise noted.) (Note 1) (Figure 5) PARAMETER SYMBOL CONDITIONS MIN TYP MAX UNITS OUTPUT DRIVER ROUT-N VCC = 8V (applied externally), IOUT = 100mA (sinking) 1.7 3.5 Driver Output Impedance ROUT-P VCC = 8V (applied externally), IOUT = 100mA (sourcing) 35 Ω COUT = 10nF, sinking 1000 Driver Peak Output Current IOUT-PEAK COUT = 10nF, sourcing 750 mA OVERVOLTAGE COMPARATOR Overvoltage Comparator Input Threshold VOV-TH VOVI rising 1.20 1.228 1.26 V Overvoltage Comparator Hysteresis VOV-HYST 125 mV Overvoltage Comparator Delay TDOVI From OVI rising above 1.228V to OUT falling, with 50mV overdrive 1.6 µs OVI Input Current IOVI VOVI = 0 to 5V -0.5 +0.5 µA THERMAL SHUTDOWN Shutdown Temperature TSHDN Temperature rising 160 oC Thermal Hysteresis THYST 15 oC Note 1: 100% production tested at +125°C. Limits over the temperature range are guaranteed by design. Note 2: Not production tested, guaranteed by design. Note 3: For the MAX15005A/B, DMAX depends upon the value of RT. See Figure 3 and the Oscillator Frequency/External Synchronization section. Note 4: The external SYNC pulse triggers the discharge of the oscillator ramp. See Figure 2. During external SYNC, DMAX = 50% for the MAX15004A/B; for the MAX15005A/B, there is a shift in DMAX with fSYNC/fOSC ratio (see the Oscillator Frequency/ External Synchronization section). Note 5: The parameter is measured at the trip point of latch, with 0 ≤ VCS ≤ 0.3V, and FB = COMP. Note 6: Slope compensation = (2.5 x 10-9)/CSLOPE mV/µs. See the Applications Information section. |
