GENERAL DESCRIPTION The ADM6305/ADM6306 are dual voltage supervisors designed to monitor two supplies and provide a reset signal to DSP- and microprocessor-based systems. Low supply current and a small form factor make these devices suitable for portable and battery-operated applications. If a monitored power supply voltage falls below the minimum voltage threshold, a single active low output asserts triggering a system reset. Once all voltages rise above the selected threshold level, the reset signal remains low for the reset timeout period. Four reset timeout options are available. The ADM6305 monitors two supplies via two adjustable resistor-programmable undervoltage reset inputs. Both RST IN1 and RST IN2 have a reset threshold of either 0.4 V or 1.23 V depending on the particular model; that is, the RST IN1 and RST IN2 threshold of the ADM6305DxARJZ model is 1.23 V, while in the case of ADM6305DxARJZ1 model, it is 0.4 V. The VCC input of the ADM6305 is not a monitored input. The ADM6306 has one adjustable undervoltage reset input, RST IN, which features a choice of reset threshold, 0.4 V or 1.23 V (see the Ordering Guide for more information). The ADM6306 incorporates a variety of internally pretrimmed VCC undervoltage threshold options for monitoring supply voltages in increments between 2.5 V and 5 V. The ADM6306 also includes a manual reset input. The ADM6305/ADM6306 RESET output remains valid as long as VCC exceeds 0.9 V. The ADM6305/ADM6306 are available in a 5-lead SOT-23 package. These devices are specified over the temperature range of −40°C to +125°C. Rev. A Information furnished by Analog Devices is believed to be accurate and reliable.

A | Page 7 of 12 ADM6305/ADM6306 Data Sheet THEORY OF OPERATION The ADM6305/ADM6306 are compact, low power supervisory circuits capable of monitoring two voltage rails. If a monitored voltage drops below its associated threshold, the active low reset output asserts low. The ADM6305 monitors two supplies via two adjustable resistor-programmable undervoltage reset inputs. Both RST IN1 and RST IN2 have a reset threshold of either 0.4 V or 1.23 V depending on the particular model; that is, the RST IN1 and RST IN2 threshold of the ADM6305DxARJZ model is 1.23 V, while in the case of ADM6305DxARJZ1 model, it is 0.4 V. The VCC input of the ADM6305 is not a monitored input. The ADM6306 has one adjustable undervoltage reset input, RST IN, which features a choice of reset threshold, 0.4 V or 1.23 V (see the Ordering Guide for more information). The ADM6306 incorporates a variety of internally pretrimmed VCC undervoltage threshold options for monitoring supply voltages in increments between 2.5 V to 5 V. The ADM6306 also includes a manual reset input. INPUT CONFIGURATION The threshold voltage at an adjustable input is either 0.4 V or 1.23 V. To monitor a voltage greater than the typical adjustable threshold, VRSTH, connect a resistor divider network to the circuit as depicted in Figure 14, where R1 R2 VTH VRSTH R2 on this input. The ADM6305/ADM6306 are powered via VCC. Figure 9 shows the maximum transient duration vs. VCC reset threshold overdrive, for which reset pulses are not generated. Figure 9 depicts the maximum pulse width that a negative going VCC transient may typically have without causing RESET to be asserted. As the amplitude of the transient increases, the maximum allowable pulse width decreases. The addition of a bypass capacitor on VCC provides additional transient immunity. RESET OUTPUT CONFIGURATION The ADM6305/ADM6306 are available in a choice of four reset timeouts. Once the monitored supplies rise above their associated threshold level, the RESET signal remains low for the reset timeout period before deasserting. Subsequently, if a monitored supply falls below its associated threshold, the RESET output reasserts. The open-drain RESET output of the ADM6305/ADM6306 remains valid as long as VCC exceeds 0.9 V. The ADM6305 remains in UVLO when VCC is below 1.5 V. The RESET output is controlled by RTS INx if VCC exceeds 2.5 V. The open-drain RESET output allows the ADM6305 and ADM6306 to interface easily with microprocessors and devices with bidirectional reset pins. Connecting the supervisory devices RESET output directly to the microcontrollers RESET pin with a single pull-up resistor allows either device to issue a system reset (see Figure 15). VIN VCC R1 R2 VRSTH 09345-014 RESET The high input impedance (leakage of ±25 nA) of the adjustable inputs minimizes the offset error caused by the leakage current and external resistor divider. This allows the user to apply a divider with large resistance to minimize the loss. The offset voltage caused by the leakage current is calculated by R1 × ±25 nA. There is no hysteresis associated with the 0.4 V adjustable inputs; instead, a time-based glitch filter to prevent false triggering is used. The glitch filter avoids the need to use a portion of the operating supply range to provide hysteresis MICROPROCESSOR RESET Figure 15. Interfacing to Microprocessors with Bidirectional RESET Output Figure 14. Setting the Adjustable Monitor The RST INx inputs are designed to ignore fast voltage transients (see Figure 11 and Figure 12). Increase the noise immunity by connecting a 0.1 μF bypass capacitor between RST INx and ground. Note that adding capacitance to RST INx slows the overall response time of the device. RPULL-UP 09345-015 ADM6305/ ADM6306 MANUAL RESET The ADM6306 features a manual reset input (MR) which, when driven low, asserts the reset output. When MR transitions from low to high, reset remains asserted for the duration of the reset active timeout period before deasserting. The MR input has a 63.5 kΩ internal pull-up resistor so that the input is always high when unconnected. An external push-button switch can be connected between MR and ground so that the user can generate a reset. Debounce circuitry is integrated on-chip for this purpose. Noise immunity is provided on the MR input, and fast, negative-going transients of up to 0.1 μs (typical) are ignored. If required, a 0.1 μF capacitor between MR and ground provides additional noise immunity. Rev. A | Page 8 of 12 Data Sheet ADM6305/ADM6306 OPTIONS Table 6.
