1 Microcontroller Supervisory Circuit with Push-Pull Output FEATURES Holds microcontroller in reset until supply voltage reaches stable operating level Resets microcontroller during power loss Precision monitoring of 3V, 3.3V, and 5V systems 7 voltage trip points available Active low pin (MCP1) or active high (MCP11) Push-pull output Holds / for 35 ms (typical) Guaranteed / to = 1.V Accuracy of ±125mV for 5V systems and ±75mV for 3V systems over temperature 45 µa typical operating current Temperature range: - Industrial (I): -4 C to +85 C DESCRIPTION The MCP1/11 is a voltage supervisory device designed to keep a microcontroller in reset until the system voltage has reached the proper level and stabilized. It also operates as protection from brown-out conditions when the supply voltage drops below a safe operating level. Both devices are available with a choice of seven different trip voltages and both have push-pull outputs. The MCP1 has a low active pin and the MCP11 has a high active pin. The MCP1/11 will assert the / signal whenever the voltage on the pin is below the trip-point voltage.

APPLICATIONS INFMATION 2.1 The Need for Supervisory Circuits For many of today s microcontroller applications, care must be taken to prevent low power conditions that can cause many different system problems. The most common causes are brown-out conditions where the system supply drops below the operating level momentarily, and the second, is when a slowly decaying power supply causes the microcontroller to begin executing instructions without enough voltage to sustain SRAM and producing indeterminate results. 5V SUPPLY VOLTAGE TRANSIENT DURATION TIME (V TRIPMIN - ) V TRIPMAX V TRIPMIN MICROCONTROLLER bypass capacitor MCP1 VSS FIGURE 2-1: Typical Application MCLR 2.2 Negative Going Transients Many system designers implementing P circuits are concerned about the minimum pulse width required to cause a reset. Figure 2-2 shows typical transient duration vs. reset comparator overdrive for which the MCP1/11 will not generate a reset pulse. It shows that the farther below the trip point the transient pulse goes, the duration of the pulse required to cause a reset gets shorter. A.1 µf bypass cap mounted as close as possible to the pin provides additional transient immunity. TRANSIENT DURATION (µs) Transients below the curve will NOT cause a reset V TRIP - (V) T A = +25 C Transients above the curve will cause a reset FIGURE 2-2: Typical Transient Response Preliminary DS11187D-page 3
4 2.3 Effect of Temperature on Timeout Period (t RPU ) The timeout period (t RPU ) determines how long the device remains in the reset condition. This is controlled by an internal RC timer and is effected by both and temperature. The graph shown in Figure 2-3 shows typical response for different values and temperatures. 7 NMALIZED THRESHOLD* (V TRIP ) TIMEOUT PERIOD (T RPU ) (MS) 6 = 6V 5 = 5V 4 3 = 4V 2 = 3V * Multiply value at 25 C by this factor to determine the value at temperature 8 1 FIGURE 2-5: Normalized V TRIP vs. Temperature 8 = 2.5V 7 = 1.5V = 3.5V 6 FIGURE 2-3: Typical t RPU vs. Temperature Operating Current (µa) 6 = 5V 5 = 5.5V 4 3 = 3V = 4V FIGURE 2-4: I DD vs. Temperature V OL (mv) 5 4 = 4.5V T A = +25 C I OL (ma) FIGURE 2-6: V OL vs. I OL NMALIZED I OL * * Multiply value at 25 C by this factor to determine the value at temperature FIGURE 2-7: Normalized I OL vs. Temperature DS11187D-page 4 Preliminary 1999
