Product details
Overview
ISL88001IE26Z-T from Renesas Electronics is an ultra-low-power 3-pin voltage supervisor IC with push-pull active-low reset output, 2.63V fixed threshold, ±1.2% accuracy, 190ms power-on reset timeout, and operation down to VDD = 1V. It monitors single-supply rails in microcontroller systems, portable equipment, and battery-powered instrumentation.
For engineers reviewing the ISL88001IE26Z-T datasheet, ISL88001IE26Z-T pinout, ISL88001IE26Z-T application, or ISL88001IE26Z-T equivalent, key selection criteria include supply current (160nA typ), reset validity at low VDD (1V), SC-70 package footprint, and compatibility with 2.6V logic rails requiring precise brownout detection.
Technical Context
The ISL88001IE26Z-T integrates a precision bandgap reference, comparator with hysteresis, and POR circuitry to assert reset when VDD falls below 2.63V (±1.2%) or during initial power-up. Its internal architecture ensures immunity to supply transients and stable operation across -40°C to +85°C.
It delivers a push-pull RST output that drives LOW during reset assertion and HIGH (VDD − 0.2V min) otherwise, eliminating external pull-up components. The device draws only 160nA typical supply current at 1.8V, enabling multi-year battery life in always-on monitoring applications.

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX809SEUR+T | 2.63V threshold, SOT-23-3, 1.2µA supply current, 240ms POR | Higher quiescent current limits battery life; larger SOT-23 footprint increases board area | Select when existing layout uses SOT-23 and higher IDD is acceptable |

FAQ
What is the exact reset threshold voltage of the ISL88001IE26Z-T?
The ISL88001IE26Z-T has a nominal reset threshold of 2.63V with ±1.2% accuracy over -40°C to +85°C. At +25°C, the typical value is 2.630V, with min/max bounds of 2.598V and 2.662V respectively. This fixed threshold is factory-trimmed and requires no external components.
Does the ISL88001IE26Z-T require an external pull-up resistor on the RST pin?
No, the ISL88001IE26Z-T features a push-pull RST output and does not require an external pull-up resistor. During reset assertion, RST is actively driven LOW; when inactive, it is actively driven HIGH to VDD − 0.2V minimum. This simplifies design and reduces BOM count.
What is the minimum supply voltage at which the ISL88001IE26Z-T can assert a valid reset signal?
The ISL88001IE26Z-T guarantees valid reset assertion down to VDD = 1.0V. This ensures fail-safe behavior during deep brownout conditions where other supervisors may lose functionality, making it ideal for battery-powered systems nearing end-of-life.
Which package type is used by the ISL88001IE26Z-T, and what are its dimensions?
The ISL88001IE26Z-T uses the 3-lead SC-70 package (JEDEC MO-203AA, Renesas pkg drawing P3.049), with body dimensions of 1.25mm × 0.80mm × 0.50mm. Its 0.65mm lead pitch and 0.8mm width enable denser layouts than standard SOT-23 packages.
How does the ISL88001IE26Z-T compare to the ISL88002IE26Z-T and ISL88003IE26Z-T variants?
The ISL88001IE26Z-T differs from ISL88002IE26Z-T (open-drain RST) and ISL88003IE26Z-T (push-pull active-high RST) solely in reset polarity and output structure. All three share identical 2.63V threshold, 160nA supply current, 190ms POR, and SC-70 packaging-enabling drop-in replacement with only minor schematic adjustments.
