UM809/810 3-Pin Microprocessor Reset Circuits UM809/810 SOT323/SOT23-3 General Description The UM809/810 series are ultra low current, cost effective system supervisory circuits designed to monitor the power supplies in digital systems. They provide a reset signal to the host processor when necessary, offer excellent circuit reliability & low cost by eliminating external component and adjustment when used with +5V, +3.3V, +3.0V or other voltage powered circuits. The reset output is driven active within 10µs of power supply falling through the reset voltage threshold. Reset is keeping active for a minimum of 140ms after system power supply has risen above the reset threshold. Reset threshold suitable for operation with variety of supply voltage are available. UM809 has an active-low reset output while UM810 has an active-high reset output. The UM809/810 are optimized to reject fast transient glitches on the power supply line, and the reset output are guaranteed to be in the correct logic state for power supply VCC down to 1V. Each of these ICs consists of a voltage reference comparator, resistors for detector threshold setting, delay generator, output driver & hysteresis circuit. The reset threshold & time delay are fixed with high accuracy internally and does not require any external adjustment. Low supply current of 3µA (VCC=3V) makes UM809/810 ideal for low power application. Both devices are available in 3 Pin SOT323 or SOT23 packages.

The UM809/810 asserts reset to prevent code-execution errors during power-up, power-down, or brownout conditions. They assert a reset signal whenever the VCC supply voltage declines below a preset threshold, keeping it asserted for at least 140ms after VCC has risen above the reset threshold. The UM809/810 has a push-pull output stage. Applications Information VCC Transient Rejection In addition to issuing a reset to the µP during power-up, power-down, and brownout conditions, the UM809/810 is relatively immune to short-duration negative-going VCC transients (glitches). Figure 9 shows typical transient duration vs. reset comparator overdrive, for which the UM809/810 do not generate a reset pulse. The graph was generated using a negative-going pulse applied to VCC, starting 0.5V above the actual reset threshold and ending below it by the magnitude indicated (reset comparator overdrive). The graph indicates the maximum pulse width a negative-going VCC transient can have without causing a reset pulse. As the magnitude of the transient increases (goes farther below the reset threshold), the maximum allowable pulse width decreases. Typically, for the UM8_L and UM8_M, a VCC transient that goes 100mV below the reset threshold and lasts 20µs or less will not cause a reset pulse. A 0.1µF bypass capacitor mounted as close as possible to the VCC pin provides additional transient immunity.

Maximum Transient Duration vs Overdrive for Glitch Rejection at 25°C Output Signal Integrity during Power-Down _____________ When VCC falls below 1V, the UM809 RESET output no longer sinks current—it becomes an _____________ open circuit. Therefore, high-impedance CMOS logic inputs connected to RESET can drift to undetermined voltages. This presents no problem in most applications since most µP and other _____________ circuitry is inoperative with VCC below 1V. However, in applications where RESET must be _____________ valid down to 0V, adding _____________ a pull-down resistor to RESET causes any stray leakage currents to flow to ground, holding RESET low (Figure 10). R1’s value is not critical; 100kΩ is large ________________________________________________________________________ http://www.union-ic.com Rev.06 Apr.2015 6/14 UM809/810 _____________ _____________ enough not to load RESET and small enough to pull RESET to ground. A 100kΩ pull-up resistor to VCC is also recommended for the UM810 if RESET is required to remain valid for VCC < 1V. _____________ Figure 10. RESET Valid to VCC=Ground Circuit Interfacing to μPs with Bidirectional Reset Pins Some µP’s (such as Motorola 68HC11) have bi-directional reset pins. Depending on the current drive capability of the processor pin, an indeterminate logic level may result in series with the output of the UM809 (Figure 11). If there are other components in the system which requires a reset signal, they should be buffered so as not to load the reset line. If the other components are required to follow the reset I/O of the μP, the buffer should be connected as shown with the solid line. ( )* for UM810 Figure 11. Interfacing to Bidirectional Reset I/O Benefits of Highly Accurate Reset Threshold Most µP supervisor circuits have reset threshold voltages between 5% and 10% below the value of nominal supply voltages. This ensures a reset will not occur within 5% of the nominal supply, but will occur when the supply is 10% below nominal. When using ICs rated at only the nominal supply ±5%, this leaves a zone of uncertainty where the supply is between 5% and 10% low, and where the reset may or may not be asserted. The UM8_ L/T/Z use highly accurate circuitry to ensure that reset is asserted close to the 5% limit, and long before the supply has declined to 10% below nominal. ________________________________________________________________________ http://www.union-ic.com Rev.06 Apr.2015 7/14 UM809/810 Package Information UM809/810 SOT323 Outline Drawing D Symbol E HE L1 L b PIN 1 Q1 e c e End View Side View A1 A A2 Top View D E HE b e Q1 A A1 A2 c L L1 DIMENSIONS MILLIMETERS INCHES Min Max Min Max 1.80 2.20 0.072 0.088 1.15 1.35 0.006 0.054 1.80 2.40 0.072 0.050 0.25 0.40 0.010 0.016 0.65BSC 0.026BSC 0.10 0.40 0.004 0.016 0.80 1.10 0.032 0.044 0.00 0.10 0.00 0.004 0.80 1.00 0.032 0.040 0.10 0.18 0.004 0.007 0.10 0.30 0.004 0.012 0.425TYP 0.017TYP Land Pattern 0.65 0.5 0.6 1.80 0.65 NOTES: 1.
