Product details
Overview
ISL88001IE16Z-TK from Renesas Electronics is an ultra-low-power 3-pin voltage supervisor IC with push-pull active-low reset output, 1.58V fixed threshold (±1.2% accuracy), 160nA supply current at 1.8V, and 190ms power-on reset timeout. It monitors VDD in battery-powered microcontroller systems where supply stability below 1V must trigger reliable reset assertion.
For engineers reviewing the ISL88001IE16Z-TK datasheet, ISL88001IE16Z-TK pinout, ISL88001IE16Z-TK application, or ISL88001IE16Z-TK equivalent, key selection criteria include its SC-70-3 package footprint, 1.58V trip point for low-voltage logic rails, immunity to supply transients, and compatibility with systems requiring reset validity down to VDD = 1V without external components.
Technical Context
The ISL88001IE16Z-TK implements a factory-programmed voltage reference comparator with hysteresis to prevent noise-induced reset chatter. Its internal POR circuit asserts reset at VDD = 1V and holds it until VDD exceeds 1.58V for ≥190ms, ensuring stable initialization of microcontrollers and FPGAs.
It operates across -40°C to +85°C with ±0.48mV/°C temperature coefficient on VTHVDD and delivers push-pull RST output capable of sourcing/sinking 10mA, eliminating need for external pull-up resistors unlike open-drain variants (e.g., ISL88002).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reset Threshold | 1.58V ±1.2% - precisely monitors 1.6V–1.8V logic supplies with minimal tolerance drift over temperature. |
| Supply Current | 160nA at VDD = 1.8V - enables multi-year operation in coin-cell-powered IoT sensors and wearables. |
| POR Timeout | 190ms typical - guarantees sufficient delay for FPGA configuration loading and oscillator stabilization before release. |
| Reset Validity Range | VDD ≥ 1V - ensures functional reset assertion even during deep brownout conditions common in battery discharge profiles. |
| Output Type | Push-pull active-low - drives reset input directly without external pull-up, reducing BOM count and PCB area. |
| Package | 3-lead SC-70 (P3.049) - 2.0 × 2.1 mm footprint ideal for space-constrained portable designs. |
| Operating Temp | -40°C to +85°C - supports industrial-grade deployment in automotive infotainment and industrial controllers. |
Pinout & Package
ISL88001IE16Z-TK is housed in a Pb-free 3-lead SC-70 plastic package (JEDEC MO-203AA, Renesas pkg drawing P3.049), measuring 2.0mm × 2.1mm × 0.95mm with 0.65mm lead pitch. The top-view pinout is standardized across ISL88001 variants.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | GND | Ground reference for internal comparator and reset driver; must be connected to system ground plane for accurate threshold sensing. |
| 2 | RST | Active-low push-pull reset output; sinks current when asserted (RST = LOW), sources current when released (RST = HIGH); compatible with standard µP reset inputs. |
| 3 | VDD | Power supply input and monitored voltage node; supplies IC bias and serves as analog input to internal voltage reference comparator. |
Key Features
| Feature | Design Value |
|---|---|
| Fixed 1.58V threshold | Enables precise supervision of 1.6V/1.8V I/O rails in modern low-power MCUs without trimming resistors or calibration. |

| 190ms POR timeout | Guarantees full initialization sequence completion for ARM Cortex-M0+ and RISC-V SoCs before software execution. |
| No external components | Eliminates need for pull-up resistors, capacitors, or voltage dividers-reducing bill-of-materials and layout complexity. |
| SC-70-3 package | Provides same board area as 0402 passives while maintaining hand-solderability and reflow compatibility. |
Applications
| Microcontroller Power-Up Sequencing | Battery-Powered Sensor Nodes |
|---|---|
Use Scenario: Ensuring reliable boot of an ARM Cortex-M4 MCU powered by a single Li-ion cell (2.8–4.2V range) with 1.8V I/O domain. IC Role / Device Role / Timing Role: Voltage supervisor providing active-low reset signal synchronized to VDD rise time and holding reset until 190ms after VDD crosses 1.58V. Use Value: Prevents corrupted register states and flash writes during unstable power ramp, eliminating field failures due to premature firmware execution. |
Use Scenario: Supervising a BLE SoC (e.g., nRF52840) operating from a CR2032 coin cell with steep discharge curve dropping below 2.0V. IC Role / Device Role / Timing Role: Monitors VDD at 1.58V threshold and asserts reset when battery falls below operational minimum, enabling graceful shutdown. Use Value: Extends usable battery life by 12–18% compared to higher-threshold supervisors, as reset triggers only at true end-of-life voltage. |
| Industrial Controller Brownout Protection | Portable Medical Device Power Management |

IC Role / Device Role / Timing Role: Detects 3.3V rail falling below 1.58V (indicating upstream failure) and forces system reset within 15µs propagation delay. Use Value: Eliminates need for secondary monitoring circuits; immune to fast transients due to built-in hysteresis and filtering. |
Use Scenario: Supervising a glucose meter's 1.8V analog front-end and digital core powered by two AAA alkaline cells (1.0–3.2V range). IC Role / Device Role / Timing Role: Provides reset valid down to VDD = 1V, allowing continued operation through final battery discharge phase before hard shutdown. Use Value: Enables full utilization of battery capacity without premature device disable, improving patient usability per charge cycle. |
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 | 1.6V threshold (±2.5%), 1.2µA supply current, SOT-23-3 package, no 1V reset validity guarantee. | Higher power consumption limits use in multi-year battery applications; less accurate threshold reduces margin for 1.8V rail monitoring. | Select when legacy MAX809 footprint compatibility is required and 1.2µA quiescent current is acceptable. |
| TPS3808G01DBVR | Adjustable threshold (0.405–5.8V), 1.1µA supply current, 200ms timeout, requires external resistor divider. | Greater flexibility but adds BOM cost and layout area; not suitable for space-constrained designs needing fixed 1.58V. | Select when programmable threshold is needed across multiple voltage rails or when tighter timeout control (±10%) is critical. |
Compared with MAX809SEUR+T and TPS3808G01DBVR, the ISL88001IE16Z-TK delivers 7.5× lower quiescent current and ±1.2% threshold accuracy in the same SC-70 footprint-making it optimal for ultra-low-power, high-precision 1.6V–1.8V supervision where component count and battery life are primary constraints.

FAQ
What is the exact reset threshold voltage of the ISL88001IE16Z-TK and how stable is it over temperature?
The ISL88001IE16Z-TK has a nominal reset threshold of 1.58V with ±1.2% accuracy over -40°C to +85°C. Its voltage threshold temperature coefficient is 0.48mV/°C, meaning total drift across the full temperature range is ≤±25mV-verified in Figure 10 of the FN6174 datasheet. This stability ensures consistent brownout detection in automotive and industrial environments.
Does the ISL88001IE16Z-TK require an external pull-up resistor on the RST pin?
No, the ISL88001IE16Z-TK features a push-pull RST output and does not require an external pull-up resistor. Its RST pin actively drives HIGH (to VDD) when released and LOW (to GND) when asserted, making it compatible with standard µP reset inputs without additional components-unlike open-drain alternatives such as the ISL88002.
Can the ISL88001IE16Z-TK operate reliably when the supply voltage drops below 1.8V?
Yes-the ISL88001IE16Z-TK guarantees reset functionality down to VDD = 1V, as confirmed in the datasheet's "Reset Signal Valid Down to VDD = 1V" specification. At VDD = 1.5V, it maintains full 1.58V threshold accuracy and 190ms POR timeout, enabling robust operation during deep battery discharge in portable devices.
What is the package type and dimensions of the ISL88001IE16Z-TK?
The ISL88001IE16Z-TK uses a Pb-free 3-lead SC-70 package (Renesas drawing P3.049), with dimensions of 2.0mm × 2.1mm × 0.95mm and 0.65mm lead pitch. It complies with JEDEC MO-203AA and EIAJ SC70 standards, offering identical board area to 0402 passives while supporting standard reflow profiles including Pb-free peak temperatures up to 260°C.
How does the ISL88001IE16Z-TK compare to the MAX809 series in terms of power consumption and accuracy?
The ISL88001IE16Z-TK consumes only 160nA supply current-over 7× lower than the MAX809SEUR+T's 1.2µA-and offers ±1.2% threshold accuracy versus ±2.5% for the MAX809. Both are pin-compatible, but the ISL88001IE16Z-TK's lower power and tighter tolerance make it superior for battery-critical and precision-rail applications.
