Product details
Overview
ISL88002IE26Z-T from Renesas Electronics is an ultra-low-power, open-drain voltage supervisor IC designed for precise monitoring of 2.63V power rails in space-constrained systems. It delivers ±1.2% threshold accuracy, 160nA supply current, and a 190ms power-on reset timeout, and is used to ensure reliable microprocessor startup and brownout protection in battery-powered instrumentation.
For engineers reviewing the ISL88002IE26Z-T datasheet, ISL88002IE26Z-T pinout, ISL88002IE26Z-T application, or ISL88002IE26Z-T equivalent, this page provides verified technical context, package mapping, functional pin definitions, real-world use cases, and validated alternative options for industrial and portable embedded designs.
Technical Context
The ISL88002IE26Z-T implements a factory-trimmed bandgap reference comparator with hysteresis to detect falling VDD below its fixed 2.63V trip point (±1.2% over −40°C to +85°C), asserting an active-low open-drain RST signal. Its internal POR circuit activates at VDD = 1V to guarantee reset assertion during initial power-up.
It operates across 1.8V–5.5V supply range with supply current as low as 160nA at 1.8V, and supports external pull-up resistor selection (5kΩ–100kΩ) on the RST line to interface with diverse logic families while maintaining noise immunity and transient immunity per design specification.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reset Threshold | 2.63V nominal, ±1.2% accuracy ensures stable detection of 2.6V rail collapse without false triggers. |
| Supply Current | 160nA typical at 1.8V enables multi-year operation in coin-cell–powered IoT sensors. |
| POR Timeout | 190ms minimum delay guarantees µP/µC remains held in reset until VDD stabilizes post-power-up. |
| Reset Output Type | Active-low open-drain RST requires external pull-up; compatible with mixed-voltage I/O domains. |
| Operating Temp | −40°C to +85°C industrial range supports deployment in automotive cabin electronics and industrial controllers. |
| Reset Valid Down To | VDD = 1V ensures reliable reset assertion even during deep brownout conditions. |
| Package | 3-lead SC-70 (P3.049), 1.8mm × 2.2mm footprint saves PCB area vs. SOT-23 alternatives. |
Pinout & Package
ISL88002IE26Z-T is housed in a Pb-free 3-lead SC-70 package (JEDEC MO-203AA, drawing P3.049), measuring 1.80mm × 2.20mm × 0.95mm with gull-wing leads. The package is RoHS-compliant and rated MSL1 for lead-free reflow.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | GND | Ground reference for internal comparator and reset logic; must be connected to system ground plane. |
| 2 | RST | Active-low open-drain reset output; requires external pull-up resistor (5kΩ–100kΩ) to host VDD or logic rail. |
| 3 | VDD | Power supply input and monitored voltage source; supplies IC bias and serves as threshold reference input. |
Key Features
| Feature | Design Value |

Equivalent & Alternatives
The following parts are listed as comparable options for similar voltage supervisor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX809SEUR+T | 2.63V threshold, SOT-23-3, push-pull RST, 1.2µA ICC - 7.5× higher quiescent current than ISL88002IE26Z-T. | Not suitable for multi-year battery operation; better for cost-sensitive, non-battery applications. | Select when push-pull output is required and ultra-low power is not critical. |
| TPS3808G12QDBVRQ1 | 1.2V adjustable threshold via external resistor; 1.8µA ICC; AEC-Q100 qualified; no fixed 2.63V option. | Requires external components and layout tuning; intended for automotive rather than portable industrial use. | Select only if AEC-Q100 qualification is mandatory and adjustable threshold justifies added complexity. |
Compared with MAX809SEUR+T and TPS3808G12QDBVRQ1, the ISL88002IE26Z-T uniquely combines fixed 2.63V accuracy, 160nA supply current, and SC-70 footprint-making it optimal for compact, long-life, industrial-grade supervision where minimal BOM count and board area are critical.

FAQ
What is the exact reset threshold voltage of the ISL88002IE26Z-T?
The ISL88002IE26Z-T has a nominal reset threshold voltage of 2.63V, with guaranteed accuracy of ±1.2% over the full −40°C to +85°C operating temperature range. This value is factory-trimmed and specified in the Electrical Specifications table on page 8 of FN6174 Rev 3.00.
Does the ISL88002IE26Z-T require an external pull-up resistor on the RST pin?
Yes, the ISL88002IE26Z-T features an open-drain RST output and requires an external pull-up resistor between RST and the target logic rail (typically 3.3V or 5V). The datasheet recommends values from 5kΩ to 100kΩ, balancing speed, power, and noise immunity for the ISL88002IE26Z-T application.
What package type and dimensions does the ISL88002IE26Z-T use?
The ISL88002IE26Z-T uses a Pb-free 3-lead SC-70 package (JEDEC MO-203AA, drawing P3.049), with body dimensions of 1.80mm × 2.20mm × 0.95mm. Lead pitch is 0.65mm, and it is MSL1 rated for lead-free reflow per J-STD-020 - confirmed in the Package Outline Drawings section of FN6174.
Can the ISL88002IE26Z-T operate reliably down to 1V supply voltage?
Yes, the ISL88002IE26Z-T asserts reset down to VDD = 1V, enabling robust power-on reset functionality even during severe brownout conditions. Its internal POR circuit activates at exactly 1V, and the reset signal remains valid throughout the entire 190ms timeout period - a key specification verified in the Absolute Maximum Ratings and Principles of Operation sections.
Is the ISL88002IE26Z-T pin-compatible with other members of the ISL8800x family?
Yes, the ISL88002IE26Z-T shares identical pinout and SC-70 package with all ISL88001/ISL88002/ISL88003 variants, including ISL88002IE23Z-T and ISL88002IH26Z-T. Pin 1 is GND, Pin 2 is RST (open-drain), and Pin 3 is VDD - consistent across the family and documented in the Pin Descriptions and Functional Block Diagrams on pages 2 and 9 of FN6174.
