A variety of factory-trimmed threshold voltages and supply tolerance are available to optimize the PT7M6709/6714 for specific applications. The selection includes input options for monitoring 5.0V, 3.3V, 3.0V, 2.5V and 1.8V voltages. Additional highinput impedance comparator options can be used as adjustable voltage monitors, general-purpose compareators, or digital-level translators.

The PT7M6714 provides an active-low, open-drain RESET output with integrated reset timing and three power-fail comparator outputs. Each of the monitored voltages is available with trip thresholds to support power-supply tolerances of either 5% or 10% below the nominal voltage. An internal bandgap reference ensures accurate trip thresholds across the operating temperature range.

The four open-drain outputs have weak (10μA) internal pull-ups to Vcc, allowing them to interface easily with other logic devices. The weak internal pull-ups can be overdriven by external pull-ups to any voltage from 0V to 5.5V. Internal circuitry prevents current flow from the external pull-up voltage to Vcc. The outputs can be wire-ORed for a single power-good signal. The PT7M6709 quad voltage monitor includes an accurate reference, four precision comparators, and a series of internally trimmed resistor-divider networks to set the factory-fixed threshold options. The resistor networks scale the specified IN_reset voltages to match the internal reference/comparator voltage. Adjustable threshold options bypass the internal resistor networks and connect directly to one of the comparator inputs (an external resistor-divider network is required for threshold matching). The PT7M6709 monitors power supplies with either 5% or 10% tolerance specifications, depending on the selected version. Additional high-input-impedance comparator options can be used as an adjustable voltage monitor, general-purpose comparator, or digitallevel transiator. The PT7M6714 quad voltage monitor/reset offers one fixed input with internal timing for P reset, three power-fail comparators, and a manual reset input( MR ). RESET asserts low when Vcc drops below its threshold or MR is driven low. Each of the three power-fail inputs connects directly to one of the comparator inputs. When any input is higher than the threshold level, the output is high. The output goes low as the input drops below the threshold voltage. The undervoltage lockout circuitry remains active and all outputs remain low with Vcc down to 1V(Fig.4 and Fig.5). Application Information Hysteresis The PT7M6709/PT7M6714 has built-in hysteresis which is typically 0.3% of the threshold voltage, so external resistive network used for causing hysteresis is not required. Under-voltage Detection Circuit The open-drain outputs of PT7M6709/PT7M6714 can be configured to detect an under-voltage condition. The PT7M6709/PT7M6714 can also be used in applications such as system supervisory monitoring, multi-voltage level detection, and Vcc bar graph monitoring. 12-07-0002 PT0235-2 7 07/05/12 PT7M6709/6714 Multi-voltage Supervisor ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||| Window Detection A window detector circuit uses two auxiliary inputs in a configuration such as the one shown in Fig 6. External resistors R1-R4 set the two threshold voltages (VTH1 and VTH4 ) of the window detector circuit. Window width (ΔVTH ) is the difference between the threshold voltages.(Fig 7). Adjustable Input The PT7M6709 offers several monitor options with adjustable reset thresholds. The PT7M6714 has three monitored inputs with adjustable thresholds. The threshold voltage at each adjustable IN_(PFI_) input is typically 0.62V. To monitor a voltage>0.62V, connect a resistor-divider network to the circuit. VINTH =0.62V×(R1+R2)/R2 OR R1=R2×(VINTH /0.62V-1) Unused Input The unused inputs (except the adjustable) are internally connected to ground through the lower resistors of the threshold-setting resistor pairs. The adjustable input, however, must be connected to ground if unused. Reset Output The PT7M6714 RESET output asserts low when Vcc drops below its specified threshold or MR asserts low and remains low for the reset timeout period(>=140ms) after Vcc exceeds its threshold and MR deasserts. The output is open drain with a weak (10μA) internal pull up to Vcc. For many applications, no external pull up resistor is required to interface with other logic devices. An external pull resistor to any voltage from 0V to 5.5V overdrives the internal pull up if interfacing to different logic supply voltage. Internal circuitry prevents reverse current flow from the external pullup voltage to Vcc. Manual Reset Input A logic low on MR asserts RESET low. RESET remains asserted while MR is low, and during the reset timeout Period (140ms min) after MR returns high. The MR input has an internal 20kΩ pullup resistor to Vcc, so it can be left open if unused. Drive MR with TTL or CMOS-logic levels, or with open-drain/collector outputs. Connect a normally open momentary switch from MR to GND to create a manual reset function; external debounce circuitry is not required. If MR is driven from long cables or if the device is used in a noisy environment, connecting a 0.1μF capacitor from MR to GND provides additional noise immunity. Resetting the μP from a second voltage (PT7M6714) The PT7M6714 can be configured to assert a reset from a second voltage by connecting the power-fail output to manual reset. As the VPFI_ falls below its threshold, PFO goes low and asserts the reset output for the reset timeout period after the manual reset input is deasserted. (Please See Typical Application Circuit.) Power-Supply Bypassing and Grounding The PT7M6709/ PT7M6714 operate from a single 2.0V to 5.5V supply. In noise applications, bypass Vcc with a 0.1μF capacitor as close to Vcc as possible. 12-07-0002 PT0235-2 8 07/05/12 PT7M6709/6714 Multi-voltage Supervisor ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||| VTH1=(1+ R2 PT7M6709 R1 )VREF R2 1 IN1 Vcc 10 R1 INPUT R4 R3 2 IN2 PWRGD1 9 3 IN3 PWRGD2 8 4 IN4 PWRGD3 7 5 GND PWRGD4 6 +5V OUT VREF=0.62V VTH1=(1+ R4 R3 )VREF Fig.6 Window Detection Fig.7 Output Response of Window Detector Circuit Fig.8 Setting the Auxiliary Monitor Fig.9 RESET Output Timing Diagram 12-07-0002 PT0235-2 9 07/05/12 PT7M6709/6714 Multi-voltage Supervisor ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||| Typical Application Circuit 2.0V TO 5.5V MAY BE ONE OF THE MONITORED VOLTAGES PT7M6709 SUPPLIES TO BE MONITORED Vcc 1 IN1 Vcc 10 2 IN2 PWRGD1 9 3 IN3 PWRGD2 8 4 IN4 PWRGD3 7 5 GND PWRGD4 SYSTEM LOGIC μP 6 Fig.10 Typical Application Circuit of PT7M6709 3.3V SUPPLY Vcc PT7M6714 5V SUPPLY 9V SUPPLY VBATT Vcc 10 Vcc PFI1 RESET 9 RESET 3 PFI2 PFO1 8 4 PFI3 PFO2 7 I/O 5 GND PFO3 6 I/O 1 MR 2 μP Fig.11 Typical Application Circuit of PT7M6714 12-07-0002 PT0235-2 10 07/05/12 PT7M6709/6714 Multi-voltage Supervisor ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||| Mechanical Information MSOP-10 PKG.
