Product details
Overview
ISL88002IE26Z-TK from Renesas Electronics is an ultra-low-power 3-lead voltage supervisor IC with open-drain active-low reset output, 2.63V fixed threshold, ±1.2% accuracy, 160nA supply current, and 190ms power-on reset timeout-designed for brownout detection in battery-powered microcontroller systems.
For engineers reviewing the ISL88002IE26Z-TK datasheet, ISL88002IE26Z-TK pinout, ISL88002IE26Z-TK application, or ISL88002IE26Z-TK equivalent, key selection criteria include reset output type (open-drain), VDD monitoring down to 1V, hysteresis-enabled noise immunity, and SC-70 package compatibility with space-constrained portable designs.
Technical Context
The ISL88002IE26Z-TK implements a precision bandgap-based voltage reference comparator with factory-trimmed 2.63V trip point and 1% hysteresis to prevent oscillation during slow-rising or noisy supply transitions. Its internal POR circuit asserts reset at VDD ≥ 1V and holds it for 190ms after VDD exceeds threshold.
It operates across -40°C to +85°C with 0.48mV/°C temperature coefficient and supports push-pull or open-drain RST configurations-this variant uses open-drain output requiring external pull-up (5kΩ–100kΩ) and delivers VOL ≤ 0.4V at 0.5mA sink current.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reset Threshold | 2.63V ±1.2% - precisely monitors 2.6V rails; valid over full -40°C to +85°C range |
| Supply Current | 160nA typical - enables multi-year battery life in always-on supervision applications |
| POR Timeout | 190ms - ensures stable MCU initialization after power-up or brownout recovery |
| Minimum VDD for Reset | 1V - guarantees reliable reset assertion even during deep brownouts |
| Output Type | Active-low open-drain - allows wired-OR reset bus sharing and flexible logic-level translation |
| Hysteresis | 1% - prevents false resets due to supply ripple or transient noise on VDD |
| Operating Temp | -40°C to +85°C - qualified for industrial and portable equipment environments |
Pinout & Package
ISL88002IE26Z-TK is housed in a Pb-free 3-lead SC-70 package (JEDEC MO-203AA, pkg drawing P3.049), measuring 2.2mm × 2.0mm × 0.9mm with 0.65mm lead pitch. The compact footprint suits high-density PCB layouts in handheld and wearable devices.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | GND | Ground reference for internal comparator and reset logic; must be low-impedance connection |
| 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 and provides input to threshold comparator |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low quiescent current | 160nA enables >10-year coin-cell operation in always-on monitoring circuits |
| ±1.2% threshold accuracy | Eliminates need for external calibration; supports tight 2.6V supply tolerance requirements |
| 190ms POR timeout | Guarantees sufficient time for MCU oscillator stabilization and register initialization |
| Reset valid down to VDD = 1V | Ensures fail-safe behavior during severe undervoltage conditions before shutdown |
| Immunity to power transients | Hysteresis and internal filtering prevent spurious resets from ESD or switching noise |

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 supply current | Higher current draw limits battery life; push-pull eliminates need for external pull-up | Select when board layout lacks space for pull-up resistor or when faster RST rise time is required |

FAQ
What is the reset output configuration of the ISL88002IE26Z-TK?
The ISL88002IE26Z-TK features an active-low open-drain RST output. This requires an external pull-up resistor (5kΩ–100kΩ) to the host logic rail and enables wired-OR reset bus architectures. Unlike push-pull variants (e.g., ISL88001/ISL88003), it does not drive high internally-ensuring interoperability with mixed-voltage systems and simplifying level-shifting.
What is the minimum VDD voltage at which ISL88002IE26Z-TK can assert a valid reset signal?
The ISL88002IE26Z-TK asserts a valid reset signal down to VDD = 1V. This capability ensures fail-safe operation during deep brownout conditions, allowing the device to hold downstream logic in reset even as the supply collapses-critical for preventing data corruption in battery-powered systems approaching end-of-life.
How accurate is the 2.63V threshold voltage of ISL88002IE26Z-TK over temperature?
The ISL88002IE26Z-TK's 2.63V threshold is specified to ±1.2% over -40°C to +85°C, with a temperature coefficient of 0.48mV/°C. At +85°C, the worst-case deviation remains within ±1.2%, ensuring consistent trip-point performance without external calibration-validated per datasheet Table "VTHVDD" for part marking "226".
Does ISL88002IE26Z-TK require external components for basic operation?
No, the ISL88002IE26Z-TK requires no external components for core supervision functionality. Only an external pull-up resistor on the RST pin is needed due to its open-drain output. No capacitors, resistors, or trimming networks are required-reducing BOM count, PCB area, and design validation effort while maintaining ±1.2% threshold accuracy.
What package type and RoHS status does ISL88002IE26Z-TK use?
The ISL88002IE26Z-TK is supplied in a Pb-free 3-lead SC-70 package (JEDEC MO-203AA, pkg drawing P3.049) with NiPdAu e4 termination finish. It is fully RoHS compliant, MSL-1 rated, and compatible with both SnPb and Pb-free reflow profiles per IPC/JEDEC J-STD-020-ensuring manufacturability in modern SMT lines without process modification.
