12 / 25 page High-Voltage, Micropower, Single/Dual Linear Regulators with Supervisory Functions 12 ______________________________________________________________________________________ Detailed Description The MAX6791–MAX6796 ultra-low-quiescent-current, single-/dual-output, high-input-voltage linear regulators operate from 5V to 72V. The MAX6791–MAX6794 fea- ture dual regulators that deliver up to 150mA of load current per output. One output is available with preset output-voltage options (+1.8V, +2.5V, +3.3V, and +5.0V) and can be adjusted to any voltage between +1.8V to +11V using an external resistive-divider at SET1. The other output provides a fixed 5V output volt- age. The MAX6795/MAX6796 feature a single regulator that delivers up to 300mA of current with preset output- voltage options (+1.8V, +2.5V, +3.3V, and +5.0V) or can be adjusted to any voltage between +1.8V to +11V. All devices include an integrated µP reset circuit with a fixed/adjustable reset and watchdog timeout period. The MAX6791–MAX6796 monitor OUT/OUT1 and assert a reset output when the output falls below the reset threshold. Regulators The single and dual regulators accept an input voltage from 5V to 72V. The MAX6791–MAX6796 offer fixed preset output voltages of +1.8V, +2.5V, +3.3V, and +5V, or an adjustable output voltage of +1.8V to +11V, selected using an external resistive-divider network connected between OUT1/OUT, SET1/SET, and GND (see Figure 1). In addition to an adjustable output, the MAX6791–MAX6794 feature a fixed 5V output voltage. Reset Output The reset output is typically connected to the reset input of a µP. A µP’s reset input starts or restarts the µP in a known state. The MAX6791–MAX6796 supervisory circuits provide the reset logic output to prevent code- execution errors during power-up, power-down, and brownout conditions (see the Typical Application Circuit). RESET changes from high to low whenever the monitored output voltage drops below the reset thresh- old voltage or the watchdog timeout expires. Once the monitored voltage exceeds its respective reset thresh- old voltage, RESET remains low for the reset timeout period, then goes high. Pin Description (continued) PIN MAX6791/ MAX6792 MAX6793/ MAX6794 MAX6795/ MAX6796 NAME FUNCTION —10 10, 13, 14, 15 N.C. Not Internally Connected —— 1, 2 OUT Regulator Output. Fixed +5V, +3.3V, +2.5V, +1.8V, or adjustable output (+1.8V to +11V). Connect a 10µF (min) capacitor from OUT to GND. —— 3 SET Feedback Input for Setting the OUT Voltage. Connect SET to GND to select the preset output voltage. Connect to an external resistive-divider for adjustable output operation. —— 20 ENABLE Active-High Enable Input. Drive ENABLE high to turn on the regulator. ENABLE is internally connected to ground through a 0.5µA current sink. —— — EP Exposed Pad. EP is internally connected to GND. Connect EP to the ground plane to provide a low thermal-resistance path from the IC junction to the PC board. Do not use as the electrical connection to GND. |
