Note 1: SHDN can be forced to 12V for the purpose of debugging prototype breadboards using the no-fault test mode, which dis-
ables fault protection.
Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specificatio ns is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.
ELECTRICAL CHARACTERISTICS
(Circuit of Figure 1 (MAX8796/MAX17401), Circuit of Figure 2 (MAX8797), VIN = 12V, VDD = VCC = 5V, V3P3 = 3.3V, SHDN = STDBY
= DPRSTP = ILIM = PGDIN = V CC, DPRSLPVR = GNDS = PGND = GND, R FB = 4.25k Ω, V CC_SENSE = V CSP = V CSN = 1.200V,
D0–D6 set for 1.20V (D0–D6 = 0001100 for IMVP-6, D0–D4 = 01000 for GMCH). TA = 0°C to +85°C , unless otherwise specified.
Typical values are at TA = +25°C.) (Note 2)
