19-3673; Rev 5; 10/07 Ultra-Small, Adjustable Sequencing/Supervisory Circuits The MAX6895–MAX6899 is a family of small, low-power, voltage-monitoring circuits with sequencing capability. These miniature devices offer tremendous flexibility with an adjustable threshold capable of monitoring down to 0.5V and an external capacitor-adjustable time delay. These devices are ideal for use in power-supply sequencing, reset sequencing, and power-switching applications. Multiple devices can be cascaded for complex sequencing applications. A high-impedance input with a 0.5V threshold allows an external resistive divider to set the monitored threshold. The output asserts (OUT = high or OUT = low) when the input voltage rises above the 0.5V threshold and the enable input is asserted (ENABLE = high or ENABLE = low). When the voltage at the input falls below 0.5V or when the enable input is deasserted (ENABLE = low or ENABLE = high), the output deasserts (OUT = low or OUT = high). All devices provide a capacitor-programmable delay time from when the input rises above 0.5V to when the output is asserted. The MAX689_A versions provide the same capacitor-adjustable delay from when enable is asserted to when the output asserts. The MAX689_P devices have a 1µs propagation delay from when enable is asserted to when the output asserts. The MAX6895A/P offers an active-high enable input and an active-high push-pull output. The MAX6896A/P offers an active-low enable input and an active-low push-pull output. The MAX6897A/P offers an activehigh enable input and an active-high open-drain output. Finally, the MAX6898A/P offers an active-low enable input and an active-low open-drain output. The MAX6899A/P offers an active-low enable with an activehigh push-pull output. All devices operate from a 1.5V to 5.5V supply voltage and are fully specified over the -40°C to +125°C operating temperature range. These devices are available in ultra-small 6-pin µDFN (1.0mm x 1.5mm) and thin SOT23 (1.60mm x 2.90mm) packages.

MAX6895/MAX6899 Functional Diagram OUT = high impedance (MAX6898) Low OUT = VCC (MAX6896) Detailed Description The MAX6895–MAX6899 is a family of ultra-small, lowpower, sequencing/supervisory circuits. These devices provide adjustable voltage monitoring for inputs down to 0.5V. They are ideal for use in power-supply sequencing, reset sequencing, and power-switching applications. Multiple devices can be cascaded for complex sequencing applications. Voltage monitoring is performed through a high-impedance input (IN) with an internally fixed 0.5V threshold. When the voltage at IN falls below 0.5V or when the enable input is deasserted (ENABLE = low or ENABLE = high), the output deasserts (OUT goes low or OUT goes high). When VIN rises above 0.5V and the enable input is asserted (ENABLE = high or ENABLE = low), the output asserts (OUT goes high or OUT goes low) after a capacitor-programmable time delay. With VIN above 0.5V, the enable input can be used to turn the output on or off. After the enable input is asserted, the output turns on with a capacitor-programmable delay period (A version) or with a 150ns propagation delay (P version). Tables 1, 2, and 3 detail the output state depending on the various input and enable conditions. 6 VIN > VTH High OUT = high impedance (MAX6898) Table 3. MAX6899 Output IN ENABLE VIN < VTH Low Low VIN < VTH High Low VIN > VTH Low High VIN > VTH High Low OUT Supply Input (VCC) The device operates with a VCC supply voltage from 1.5V to 5.5V. To maintain a 1.8% accurate threshold, VCC must be above 1.5V. When VCC falls below the UVLO threshold, the output deasserts. When VCC falls below 1.2V the output state cannot be determined. For noisy systems, connect a 0.1µF ceramic capacitor from VCC to GND as close to the device as possible. For the push-pull active-high output option, a 100kΩ external pulldown resistor to ground ensures the correct logic state for VCC down to 0. _______________________________________________________________________________________ Ultra-Small, Adjustable Sequencing/Supervisory Circuits Adjustable Delay (CDELAY) When VIN rises above VTH with ENABLE high (ENABLE low), the internal 250nA current source begins charging an external capacitor connected from CDELAY to GND. When the voltage at CDELAY reaches 1V, the output asserts (OUT goes high or OUT goes low). When the output asserts, CCDELAY is immediately discharged. Adjust the delay (tDELAY) from when VIN rises above VTH (with ENABLE high or ENABLE low) to OUT going high (OUT going low) according to the equation: tDELAY = CCDELAY x 4.0 x 106 + 40µs where CCDELAY is the external capacitor from CDELAY to GND. For adjustable delay devices (A version), when VIN > 0.5V and ENABLE goes from low to high (ENABLE goes from high to low) the output asserts after a tDELAY period. For nonadjustable delay devices (P version) there is a 1µs propagation delay from when the enable input is asserted to when the output asserts. Figures 2 through 5 show the timing diagrams for the adjustable and fixed delay versions, respectively. VCC VUVLO IN VTH VTH t < tPROPA ENABLE OUT tPROPA tPROPA tDELAY tDL tOFF Figure 2. MAX6895A/MAX6897A Timing Diagram _______________________________________________________________________________________ 7 MAX6895–MAX6899 Monitor Input (IN) Connect the center point of a resistive divider to IN to monitor external voltages (see R1 and R2 of the Typical Operating Circuit). IN has a rising threshold of VTH = 0.5V and a falling threshold of 0.495V (5mV hysteresis). When VIN rises above VTH and ENABLE is high (or ENABLE is low) OUT goes high (OUT goes low) after the programmed tDELAY period. When VIN falls below 0.495V, OUT goes low (OUT goes high) after a 16µs delay. IN has a maximum input current of 15nA so large-value resistors are permitted without adding significant error to the resistive divider.

MAX6899P Timing Diagram Enable Input (ENABLE or ENABLE) The MAX6895/MAX6897 offer an active-high enable input (ENABLE), while the MAX6896/MAX6898/MAX6899 offer an active-low enable input (ENABLE). With VIN above VTH, drive ENABLE high (ENABLE low) to force OUT high (OUT low) after the adjustable delay time (A versions). For P version devices, when VIN > 0.5V and enable is asserted, the output asserts after typically 150ns. The enable input has logic-high and logic-low voltage thresholds of 1.4V and 0.4V, respectively. For both versions, when VIN > 0.5V, drive ENABLE low (ENABLE high) to force OUT low (OUT high) within 150ns typ. Output (OUT or OUT) The MAX6895/MAX6899 offer an active-high, push-pull output (OUT), and the MAX6896 offers an active-low push-pull output (OUT). The MAX6897 offers an activehigh open-drain output (OUT), and the MAX6898 offers an active-low open-drain output (OUT). Push-pull output devices are referenced to VCC. Opendrain outputs can be pulled up to 28V. 10 Applications Information Input Threshold The MAX6895–MAX6899 monitor the voltage on IN with an external resistive divider (see R1 and R2 in the Typical Operating Circuit). Connect R1 and R2 as close to IN as possible. R1 and R2 can have very high values to minimize current consumption due to low IN leakage currents (±15nA max). Set R2 to some conveniently high value (1MΩ, for example) and calculate R1 based on the desired monitored voltage using the following formula: ⎡V ⎤ R1 = R2 × ⎢ MONITOR − 1⎥ VIN ⎣ ⎦ where VMONITOR is the desired monitored voltage and VIN is the detector input threshold (0.5V). ______________________________________________________________________________________ Ultra-Small, Adjustable Sequencing/Supervisory Circuits The exact value of the pullup resistors for the opendrain outputs is not critical, but some consideration should be made to ensure the proper logic levels when the device is sinking current. For example, if VCC = 2.25V and the pullup voltage is 28V, you would try to keep the sink current less than 0.5mA as shown in the Electrical Characteristics table. As a result, the pullup resistor should be greater than 56kΩ. For a 12V pullup, the resistor should be larger than 24kΩ. It should be noted that the ability to sink current is dependent on the VCC supply voltage. Typical Application Circuits Figures 8, 9, 10 show typical applications for the MAX6895–MAX6899. Figure 8 shows the MAX6895 used with a p-channel MOSFET in an overvoltage protection circuit. Figure 9 shows the MAX6895 in a lowvoltage sequencing application using an n-channel MOSFET. Figure 10 shows the MAX6895 used in a multiple-output sequencing application. Using an n-Channel Device for Sequencing In higher power applications, using an n-channel device reduces the loss across the MOSFETs as it offers a lower drain-to-source on-resistance. However, an nchannel MOSFET requires a sufficient V GS voltage to fully enhance it for a low RDS_ON. The application in Figure 9 shows the MAX6895 in a switch sequencing application using an n-channel MOSFET. Similarly, if a higher voltage is present in the system, the open-drain version can be used in the same manner. 5V BUS 1.2V INPUT 3.3V ALWAYS ON N P 0 TO 28V 1.2V OUTPUT MONITORED 3.3V ENABLE VCC ENABLE RPULLUP VCC R1 R1 OUT OUT MAX6895 MAX6897 IN IN CDELAY CDELAY R2 R2 GND Figure 8.
