In addition, the ASM705/706/813L • MicroSO package feature a 1.6 second watchdog timer. The ASM707/708 have both active-HIGH and active-LOW reset outputs but no watchdog function.

ASM70X and 5V VCC tRS 0V ASM813L assert reset to prevent code execution errors tRS 5V during power-up, power-down and brown-out conditions. RESET 0V RESET/RESET Timing The RESET/RESET signals are designed to start a µP/µC in a known state or return the system to a known state. 5V MR 0V The ASM707/708 have two reset outputs, one active-HIGH RESET and one active-LOW RESET output. The ASM813L MR externally set low 5V tMD tMR WDO 0V has only an active-HIGH output. RESET is simply the complement of RESET. Figure 1: WDI Three-state operation RESET is guaranteed to be LOW with VCC above 1.2V. During a power-up sequence, RESET remains low until the supply rises above the threshold level, either 4.65V or 4.40V. RESET goes high approximately 200ms after crossing the threshold. Manual Reset (MR) The active-LOW manual reset input is pulled high by a 250µA pull-up current and can be driven low by CMOS/TTL logic or a mechanical switch to ground. An external debounce circuit During power-down, RESET goes LOW as VCC falls below the threshold level and is guaranteed to be under 0.4V with VCC above 1.2V. is unnecessary since the 140ms minimum reset time will debounce mechanical pushbutton switches. By connecting the watchdog output (WDO) and MR, a watchdog timeout forces RESET to be generated. The In a brownout situation where VCC falls below the threshold ASM813L should be used when an active-HIGH RESET is level, RESET pulses low. If a brown-out occurs during an required. already initiated reset, the pulse will continue for a minimum of 140ms. Watchdog Timer The watchdog timer available on the ASM705/706/813L Power Failure Detection With Auxiliary Comparator monitors µP/µC activity. An output line on the processor is All devices have an auxiliary comparator with 1.25V trip point used to toggle the WDI line. If this line is not toggled within and uncommitted output (PFO) and noninverting input (PFI). 1.6 seconds, the internal timer puts the watchdog output, This comparator can be used as a supply voltage monitor WDO, into a LOW state. WDO will remain LOW until a toggle with an external resistor voltage divider. The attenuated is detected at WDI. voltage at PFI should be set just below the 1.25 threshold. As the supply level falls, PFI is reduced causing the PFO output If WDI is floated or connected to a three-stated circuit, the to transit LOW. Normally PFO interrupts the processor so the watchdog function is disabled, meaning, it is cleared and not system can be shut down in a controlled manner. counting. The watchdog timer is also disabled if RESET is asserted. When RESET becomes inactive and the WDI input sees a high or low transition as short as 50ns, the watchdog timer will begin a 1.6 second countdown.

Buffered RESET WDO will also become LOW and remain so, whenever the VCC supply voltage, VCC , falls below the device threshold level. WDO goes HIGH as soon as VCC transitions above the threshold. There is no minimum pulse width for WDO as there is for the RESET outputs. If WDI is floated, WDO Supply Voltage ASM70x µC or µP 4.7kΩ essentially acts as a low-power output indicator. RESET Input RESET GND WDI GND Bi-directional I/O Pin Figure 3: Bi-directional Reset Pin Interfacing Monitoring Voltages Other Than VCC WDO The ASM705-708 can monitor voltages other than VCC using the Power Fail circuitry. If a resistive divider is connected from the voltage to be monitored to the Power Fail input RESET (PFI), the PFO will go LOW if the voltage at PFI goes below 1.25V reference. Should hysteresis be desired, connect a resistor (equal to approximately 10 times the sum of the two resistors in the divider) between the PFI and PFO pins. A RESET capacitor between PFI and GND will reduce circuit sensitivity to input high-frequency noise. If it is desired to assert a Figure 2: Watchdog Timing RESET for voltages other than VCC then the PFO output is to be connected to the MR. Application Information VIN Ensuring That RESET is Valid Down to VCC = 0V +5V When VCC falls below 1.1V, the ASM705-708 RESET output no longer pulls down; it becomes indeterminate. To avoid the possibility that stray charges build up and force RESET to the VCC R1 MR wrong state, a pull-down resistor should be connected to the ASM70x RESET pin, thus draining such charges to ground and PFO PFI holding RESET low. The resistor value is not critical. A 100kΩ resistor will pull RESET to ground without loading it. R2 GND To µP RESET Bi-directional Reset Pin Interfacing The ASM705/6/7/8 can interface with µP/µC bi-directional reset pins by connecting a 4.7kΩ resistor in series with the RESET output and the µP/µC bi-directional RESET pin.

When the negative rail is OK, PFO will be LOW, and VCC + when the negative rail is failing (not negative enough), PFO goes HIGH (the opposite of when positive voltages are monitored). To trigger a reset, these outputs need to be R1 R3 VCC inverted: adding the resistors and transistor as shown MR achieves this. The RESET output will then have the same R4 sense as for positive voltages: good = HIGH, bad = LOW. It should be noted that this circuit’s accuracy depends on the VCC line, the PFI threshold tolerance, and the resistors.
