| Integrated Circuits (ICs) | 1 | Active | The ISL8700, ISL8701, ISL8702 family of ICs provide four delay adjustable sequenced outputs while monitoring an input voltage all with a minimum of external components. High performance DSP, FPGA, µP and various subsystems require input power sequencing for proper functionality at initial power-up and the ISL870X provides this function while monitoring the distributed voltage for over and undervoltage compliance. The ISL8700 and ISL8701 operate over the +2. 5V to +24V nominal voltage range, whereas the ISL8702 operates over the 2. 5V to +12V range. All three have a user adjustable time from UV and OV voltage compliance to sequencing start via an external capacitor when in auto start mode and adjustable time delay to subsequent ENABLE output signal via external resistors. Additionally, the ISL8702 provides an input for sequencing on and off operation (SEQ_EN) and for voltage window compliance reporting (FAULT) over the +2. 5V to +12V voltage range. Easily daisy chained for more than 4 sequenced signals. Altogether, the ISL870X provides these adjustable features with a minimum of external BOM. See Figure 1 for typical implementation. |

The most popular voltage trip points are available for standard power supplies from 1. 8V to 5. 0V (see "Ordering Information" on page 3). These reset threshold voltages are accurate to within ±1. 2% and the reset signal is valid down to 1V. Active high and active low reset outputs are available in push-pull and open drain configurations (see "Functional Block Diagrams" on page 2). The ISL88001, ISL88002, ISL88003 devices are specifically designed for low power consumption and high threshold accuracy, making them especially suitable for electronic devices and portable equipment. |
