FN8093.3 Features • Single/Dual Voltage Monitoring Supervisors • Fixed-Voltage Options Allow Precise Monitoring of +2.5V, +3.0V, +3.3V, and +5.0V Power Supplies • Dual Supervisor Has One Fixed Voltage Input and Another That is User-Adjustable Down to 0.6V. • Both RST and RST Outputs Available Unique features on the ISL88013 and ISL88015 include a watchdog timer with a 51s start-up timeout and a 1.6s normal timeout duration. On the ISL88011 and ISL88014, users can increase the nominal 200ms Power-On Reset timeout delay by adding an external capacitor to the CPOR pin. Both fixed and adjustable voltage monitors are provided by the ISL88012. Complementary active-low and active-high reset outputs are available on the ISL88011, ISL88012 and ISL88013 devices. All devices provide manual reset capability (see “Product Features Table” on page 5). • Adjustable POR Timeout Delay Options Seven preprogrammed reset threshold voltages accurate to ±1.5% over temperature are offered (see “Ordering Information” on page 3).

Pin Description RST VMON The push-pull RST output is set to VDD (HIGH) whenever 1) the device is first powered up, 2) either VDD or the voltage on VMON falls below their respective minimum voltage sense levels, 3) MR is asserted or 4) the watchdog timeout expires. The VMON pin on the ISL88012, ISL88014 and ISL88015 is a monitored input voltage that is user-adjustable. The voltage at this pin is compared against an internal 600mV reference voltage (VTHVMON) and a reset is asserted whenever the monitored voltage falls below this trip point. RST/MR This pin functions as both a reset output and a manual reset input. The RST output functions identically to the complementary RST output but is an open drain output that is pulled to GND (LOW) when reset is asserted. The MR input is an active-low debounced input to which a user can connect a push-button to add manual reset capability or drive with active low signal from a controller. WDI VDD CPOR The VDD pin is the power supply terminal. It is monitored by the ISL88011, ISL88012 and ISL88013. For these devices, the voltage at this pin is compared against an internal factory-programmed voltage trip point, VTHVDD. A reset is first asserted when the device is initially powered up to ensure that the power supply has stabilized. Thereafter, reset is again asserted whenever VDD falls below VTHVDD. The device is designed with hysteresis to help prevent chattering due to noise. The CPOR input pin lets users increase the Power-On Reset timeout delay (tPOR) by connecting a capacitor between CPOR and ground. (See Figure 3) 7 The Watchdog Input takes an input from a microprocessor and ensures that it periodically toggles the WDI pin, otherwise the internal watchdog timer runs out and reset is asserted. The internal Watchdog Timer is cleared whenever the WDI input pin sees a rising or falling edge or the device is manually reset.

VOLTAGE MONITORING TIMING DIAGRAM Principles of Operation The ISL88011 through ISL88015 devices provide those functions needed for critical voltage monitoring. These features include Power-On Reset control, customizable supply voltage supervision, Watchdog Timer capability, and manual reset assertion. By integrating all of these features into a small 5 Ld SOT-23 package and using only 5.5µA of supply current, the ISL88011 through ISL88015 devices can assist in lowering system cost, reducing board space requirements, and increasing the reliability of a system. The ISL88012, ISL88014 and ISL88015 allow users to customize the minimum voltage sense level on the VMON input pin. To do this, connect an external resistor divider network to the VMON pin in order to set the trip point to some voltage above 600mV according to the following equation (See Figure 2): ( R1 + R2 ) V INTRIP = 0.6 × -------------------------R2 (EQ. 1) Low Voltage Monitoring During normal operation, these supervisors monitor both the voltage level of VDD (ISL88011, ISL88012, ISL88013) and/or VMON (ISL88012, ISL88014, ISL88015). The device asserts a reset if any of these voltages falls below their respective trip points. The reset signal effectively prevents the system from operating during a power failure or brownout condition. This reset signal remains asserted until VDD and the voltage on VMON exceed their voltage threshold setting for the reset time delay period tPOR of 200ms (See Figure 1). R1 VMON VIN R2 ISL88012 ISL88014 ISL88015 FIGURE 2. USING VMON TO MONITOR VIN VIA RESISTORS 8 FN8093.3 August 9, 2011 ISL88011, ISL88012, ISL88013, ISL88014, ISL88015 Power-On Reset (POR) Manual Reset Applying at least 1V to the VDD pin activates a POR circuit which asserts reset (i.e., RST goes HIGH while RST goes LOW). The reset signals remain asserted until the voltage at VDD and/or VMON rise above the minimum voltage sense level for time period tPOR. This ensures that the voltages have stabilized. The manual reset input (MR) allows the user to trigger a reset by using a push-button switch. The MR input is an active-low debounced input. By connecting a push-button directly from MR to ground, the designer adds manual system reset capability (see Figure 4). Reset is asserted if the MR pin is pulled low to less than 100mV for 1µs or longer while the push-button is closed. After MR is released, the reset outputs remain asserted for tPOR (200ms) and then released. These reset signals provide several benefits: • It prevents the system microprocessor from starting to operate with insufficient voltage. VDD • It prevents the processor from operating prior to stabilization of the oscillator. ISL88011 • It ensures that the monitored device is held out of operation until internal registers are properly loaded. ISL88012 ISL88013 • It allows time for an FPGA to download its configuration prior to initialization of the circuit. Rpu RST/MR ISL88014 ISL88015 PB Adjusting POR Timeout via CPOR Pin On the ISL88011 and ISL88014, users can adjust the Power-On Reset timeout delay (tPOR) up to many times the normal tPOR of 250ms. To do this, connect a capacitor between CPOR and ground (see Figure 3). For example, connecting a 30pF capacitor to CPOR will increase tPOR from a typical 250ms to about 2.5s. NOTE: Care should be taken in PCB layout and capacitor placement in order to reduce stray capacitance as much as possible, which lengthens the tPOR timeout period. FIGURE 4. CONNECTING A MANUAL RESET PUSH-BUTTON Watchdog Timer The Watchdog Timer circuit checks microprocessor activity by monitoring the WDI input pin. The microprocessor must periodically toggle the WDI pin within tWDT (1.6s nominal), otherwise the reset signal is asserted (see Figure 5). Internally, the 1.6s timer is cleared by either a reset or by toggling the WDI input. Besides the 1.6s default timeout during normal operation, these devices also have a longer 51s timeout for start-up. During this time, a reset cannot be asserted due to the WDI not being toggled. The longer delay at power-on allows an operating system to boot, an FPGA to initialize, or the system software to initialize without the burden of dealing with the Watchdog.
