ABSOLUTE MAXIMUM RATINGS

ELECTRICAL CHARACTERISTICS

(VCC, EN (MAX5924/MAX5925), EN1 (MAX5926) = +2.25V to +13.2V; EN2 (MAX5926) = 0V; VS (see Figure 1) = +1.05V to VCC; TA =

-40°C to +85°C, unless otherwise noted. Typical values are at VCC = 5V, RL = 500

Ω from OUT to GND, CL = 1µF, SLEW = open, TA

= +25°C, unless otherwise noted.) (Note 1)

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 specifications is not implied. Exposure to

absolute maximum rating conditions for extended periods may affect device reliability.

(All voltages referenced to GND, unless otherwise noted).

GATE*.....................................................................-0.3V to +20V

All Other Pins ............-0.3V to the lower of (VCC + 0.3V) or +14V

SC_DET Current (200ms pulse width, 15% duty cycle) ...140mA

Continuous Current (all other pins) .....................................20mA

Continuous Power Dissipation (TA = +70°C)

10-Pin µMAX (derate 6.9mW/°C above +70°C) ...........556mW

16-Pin QSOP (derate 18.9mW/°C above +70°C).......1509mW

Operating Temperature Range ...........................-40°C to +85°C

Junction Temperature .....................................................+150°C
