The MAX8216 is identical, except it monitors ±15V supplies instead of ±12V. The resistors required to monitor these voltages and provide comparator hysteresis are included onchip. All comparators have open-drain outputs. These devices consume 250µA max supply current over temperature.

Block Diagram _______________Detailed Description __________Applications Information The MAX8215/MAX8216 contain 5 comparators (Figure 1). The comparator with its output labeled DOUT is distinguished from the others in that it can be set up to monitor various voltages; each of the other 4 comparators monitors a specific voltage. The DOUT comparator’s noninverting input is available external to the device; its inverting input is tied internally to the reference. The MAX8215/MAX8216 comparators have open-drain outputs. Thus, these devices require pull-up resistors for proper operation. See the Typical Operating Circuit. Open-drain outputs are useful for driving LEDs and for situations in which the comparator outputs must be connected together (i.e., wire-ORed). Bypass VDD with 0.1µF connected to PGND. When the voltage on a typical comparator’s input is at or near the voltage on the other input, ambient noise generally causes the comparator output to oscillate. The most common way to eliminate this problem is by using hysteresis. When the two comparator input voltages are equal, hysteresis causes one comparator input voltage to move quickly past the other, thus taking the input out of the region where oscillation occurs. Standard comparators need external resistors for hysteresis; these resistors are not necessary when using any of the MAX8215 and MAX8216 comparators because hysteresis is built in. 6 Hysteresis _______________________________________________________________________________________ ±5V, ±12V (±15V) Dedicated Microprocessor Voltage Monitors MAX8215/MAX8216 VTRIP2 VDD MAX8215 MAX8216 RA 7 DIN RA VHYST 1 + RB ( INPUT VOLTAGE (VS) VTRIP1 180k DOUT 9 +VS ) GND OUTPUT VOLTAGE VDD RB GND 1.24V REFERENCE ( )( VTRIP = RA + RB RB TO DETERMINE THE TRIP VOLTAGES FROM PARTICULAR RESISTOR VALUES: RA VTRIP1 = VREF 1 + RB RA VTRIP2 = (VREF + VHYST) 1 + RB VHYST = 16mV TYP ) ( VREF) Figure 2. Undervoltage/Overvoltage Comparator Using the Auxiliary Comparator Adding hysteresis to a comparator creates two trip points–one for the input voltage rising and one for the input voltage falling. When the voltage at the MAX8215/MAX8216 auxiliary comparator’s (noninverting) input falls, the threshold at which the comparator switches equals the reference voltage connected to the comparator’s inverting input. However, when the voltage at the noninverting input rises, the threshold equals the reference voltage plus the amount of hysteresis voltage built into the part. The trip point is somewhat more accurate when the hysteresis voltage is not part of the threshold voltage (i.e., when the input voltage is falling) because the tolerance of the hysteresis specification adds to the tolerance of the trip point.

Hysteresis makes this circuit more accurate when the input voltage is dropping as opposed to rising. Figure 3 illustrates the comparator’s operation. The input voltage’s direction determines at which of two trip points the comparator switches. Thus, the diagram includes arrows that indicate whether the input voltage is rising or falling. The formulas are provided for determining trip-point voltages for specified resistors and for ease in calculating appropriate resistor ratios for particular trip points.

Monitoring Supply Powering the MAX8215/MAX8216 with Undervoltage and Overvoltage Comparators The MAX8215/MAX8216 comparator outputs correctly display a low level down to 0.8V supply voltage. This is useful in undervoltage applications where the monitored power supply is also the supply connected to the VDD pin. See the section Monitoring the Supply Voltage. _______________________________________________________________________________________ 7 MAX8215/MAX8216 ±5V, ±12V (±15V) Dedicated Microprocessor Voltage Monitors +5V VTRIP2 INPUT VOLTAGE (VS) VTRIP1 0.1µF 8 2 GND +VS 3 7 +5V DIN PGND MAX8215 MAX8216 VDD OUT1 DOUT 14 680k 680k GND OUTPUT VOLTAGE (OUT1) 13 9 RESET OUTPUT VOLTAGE (DOUT) VDD tDLY GND VDD GND VTRIP1 IS FOR VS DECREASING; VTRIP2 IS FOR VS INCREASING.

Microprocessor Reset Circuit with 200ms Time Delay Monitoring the Supply Voltage The supply voltage to these devices can also be monitored by the 5V dedicated comparator and the auxiliary comparator. Figure 4 shows a circuit that monitors the voltage connected at VDD for both overvoltage and undervoltage conditions. The +5V comparator checks for undervoltage conditions while the auxiliary comparator monitors overvoltage conditions. In general, no extra supply bypassing circuitry (other than the normally recommended 0.1µF capacitor) is required when performing this function. However, using resistor values higher than 100kΩ at the auxiliary comparator’s input requires attention to eliminate potential oscillations. Also, particularly low pull-up resistor values on DOUT contribute to the likelihood of the auxiliary comparator’s oscillation. See the section Eliminating Output Oscillation. Microprocessor Reset ____________Circuit with Time Delay It is often necessary to reset a microprocessor (µP) when its supply voltage drops below a certain level. Figure 5’s circuit generates a low output when the monitored voltage drops below the 5V monitor’s threshold. Additionally, this output remains low for 200ms after the supply voltage goes above the threshold. µP reset circuits typically include this feature because it gives the µP time to be fully reset after power has been restored, and allows any capacitors in associated circuitry time to charge. Figure 6 shows this circuit’s waveforms and formulas. 8 Figure 6. Microprocessor Reset with Time Delay Waveforms Figure 7 shows Figure 5’s µP reset circuit, but with the monitored supply also powering the MAX8215. Figure 6’s waveforms and equations also apply to this circuit. The MAX8215/MAX8216 comparator outputs correctly display a low level down to a 0.8V typical supply voltage. Unused Inputs When the uncommitted comparator within the MAX8215/MAX8216 is not used, tie the unused input to either the positive supply or ground. This prevents noise generation due to the comparator output switching from one logic state to another (due to noise at the input). Output Pull-Up Resistors Pull-up resistors are required at the outputs of each comparator. Resistor values should not be less than 2.7kΩ if the outputs are pulled up to VDD. In general, save power by using higher values, e.g., ≥100kΩ. Use of higher-value resistors also minimizes the possibility of oscillations due to a spurious feedback (see the section Eliminating Output Oscillation). Input Voltage Limitation If the voltages at the various inputs are kept within the absolute maximum ratings, the device is not damaged. However, high input voltages within this range can cause the reference voltage to move. To prevent the reference voltage from changing, limit the +5V input to +17V; the -5V and -15V inputs to +1V; and the +15V input to +60V.

Within the absolute maximum ratings, the DIN input has no effect on the reference. Power-Supply Bypassing and Grounding In high-noise environments where the voltage connected to VDD may change abruptly, the reference voltage may “bounce,” causing false comparator outputs. Eliminate this problem using Figure 8’s RC bypass network. Although bypassing the reference may appear to help, Figure 8’s solution is recommended; bypassing the reference reduces its voltage change, but doing so causes a time delay prior to the reference voltage returning to its correct level. Eliminating Output Oscillation when Using the Auxiliary Comparator Although hysteresis is built into the auxiliary comparator, output oscillation problems are still possible. Oscillation can occur when a comparator’s output couples back to its inverting input through stray board capacitance. Make sure the board trace leading from the comparator output does not pass near its inverting input (or vice versa). Also, reducing the resistance connected to DIN reduces its susceptibility to picking up output signals. In Figure 9. Alternative Means for Reducing Impedance Level Seen at DIN most cases, using input resistor values on the order of 100kΩ creates no problem. Since using lower resistor values increases the supply current, another approach is to bypass the input resistors as shown in Figure 9, although this slows the circuit’s response. When much larger valued input resistors are used, high valued resistors on the output should be used. When DOUT is required to sink larger currents (i.e., when smaller pull-up resistor values are used), oscillation problems are more likely to occur. To minimize power consumption and to optimize stability, use the largest value pull-up resistor feasible for the output drive required. When lower pull-up resistor values are used, lower values for the resistors connected to the inputs can help alleviate oscillation problems. _______________________________________________________________________________________ 9 MAX8215/MAX8216 ±5V, ±12V (±15V) Dedicated Microprocessor Voltage Monitors _Ordering Information (continued) PART TEMP.
