Product details
Overview
ISL88013IH529Z-TK from Renesas Electronics (formerly Intersil) is a 5-lead SOT-23 voltage supervisor IC with fixed VDD monitoring at 2.92V ±1.5%, integrated watchdog timer (1.6s normal / 51s start-up timeout), complementary active-low and active-high reset outputs, and manual reset input - designed for reliable power-on reset and brownout protection in microprocessor-based embedded systems.
For engineers reviewing the ISL88013IH529Z-TK datasheet, ISL88013IH529Z-TK pinout, ISL88013IH529Z-TK application, or ISL88013IH529Z-TK equivalent, key selection considerations include its 2.92V VDD threshold accuracy, ultra-low 5.5µA supply current, reset validity down to VDD = 1V, immunity to supply transients, and dual RST/RST output capability for flexible system-level reset signaling.
Technical Context
The ISL88013IH529Z-TK implements a precision bandgap-based voltage reference and comparator architecture to monitor VDD against a factory-trimmed 2.92V threshold with ±1.5% accuracy over -40°C to +85°C. Its internal watchdog timer features two distinct timeout modes: a 51s start-up window to accommodate boot sequences and a 1.6s nominal timeout for runtime supervision.
Reset assertion is triggered by VDD falling below 2.92V, manual reset activation via the RST/MR pin, or watchdog timeout on the WDI input. Both RST (push-pull high) and RST (open-drain low) outputs are asserted simultaneously, enabling direct interface with diverse logic families without external pull-ups or level-shifting.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDD Threshold | 2.92V ±1.5% - ensures reliable reset assertion during 2.9V–3.0V supply brownouts |
| Supply Current | 5.5µA typical at 3.3V - enables use in battery-powered systems with multi-year standby life |
| Watchdog Timeout | 1.6s normal / 51s start-up - prevents premature reset during OS/FPGA initialization while maintaining runtime fault detection |
| Reset Validity Range | VDD ≥ 1V - guarantees functional reset signaling even during deep undervoltage conditions |
| Output Types | Complementary RST (push-pull) and RST (open-drain) - supports both active-high and active-low reset logic without external components |
| Hysteresis | 29mV at 2.92V - suppresses chatter caused by supply noise near trip point |
| Manual Reset Pulse | 1µs minimum width - accommodates standard mechanical push-button debouncing |
Pinout & Package
Package: 5-lead SOT-23 (Pb-free, RoHS compliant, JEDEC MO178AA / EIAJ SC-74 compatible).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - RST/MR | Combined active-low reset output & manual reset input | Open-drain output asserted LOW during reset; accepts active-low debounced MR signal (≤100mV, ≥1µs) |
| 2 - GND | Ground reference | Common return path for all internal circuitry and reset outputs |
| 3 - RST | Active-high push-pull reset output | Drives HIGH (to VDD) during normal operation; drives LOW during reset - no external pull-up required |
| 4 - VDD | Supply voltage and monitored input | Power source (2.0–5.5V) and primary voltage sense node for 2.92V threshold detection |
| 5 - WDI | Watchdog timer input | Edge-sensitive input requiring periodic toggle (rising/falling) within 1.6s to prevent reset assertion |
Key Features
| Feature | Design Value |
|---|---|
| Dual complementary reset outputs | RST (push-pull) and RST (open-drain) enable simultaneous interface with mixed-logic systems without external biasing |
| Factory-trimmed 2.92V threshold | ±1.5% accuracy over temperature eliminates need for external calibration or trimming resistors |
| Two-mode watchdog timer | 51s start-up timeout allows full firmware boot before supervision begins; 1.6s runtime timeout detects software hangs |
| Ultra-low quiescent current | 5.5µA max at 3.3V reduces system standby power and extends battery life in portable applications |
| Reset validity down to 1V VDD | Ensures fail-safe reset signaling even during severe undervoltage events where core logic may still be operational |
Applications
| Industrial PLC Controller Monitoring | Medical Infusion Pump Power Supervision |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar voltage supervisor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX6326UR29-T | Single active-low reset only; no watchdog timer; 2.93V threshold; 1.6µA supply current | Lacks WDI supervision and complementary outputs - suitable only for basic POR/brownout without runtime fault detection | Select when lowest possible quiescent current is critical and watchdog functionality is unnecessary |
| TPS3808G33DBVR | Adjustable threshold (0.4–5V); no WDI pin; 2.5µA supply current; 200ms fixed POR delay | Requires external resistor divider for 2.92V setting; lacks start-up watchdog window - less suited for complex boot sequences | Select when flexible threshold tuning is required and system boot time is short enough to avoid watchdog timeout |
Compared with MAX6326UR29-T and TPS3808G33DBVR, the ISL88013IH529Z-TK uniquely delivers integrated watchdog supervision with dual-mode timing, complementary reset outputs, and factory-trimmed 2.92V accuracy - making it optimal for systems requiring both robust power sequencing and runtime software health monitoring.

FAQ
What is the exact voltage threshold and accuracy of the ISL88013IH529Z-TK?
The ISL88013IH529Z-TK has a factory-programmed VDD voltage threshold of 2.92V with ±1.5% accuracy over the full -40°C to +85°C industrial temperature range. This value is confirmed in the Ordering Information table (Page 3) and Electrical Specifications (Page 6) of FN8093 Rev 5.00, where VTHVDD for ISL88013IH529 is specified as 2.88V (min), 2.92V (typ), and 2.96V (max).
Does the ISL88013IH529Z-TK support watchdog timer functionality?
Yes, the ISL88013IH529Z-TK includes a watchdog timer with two distinct timeout periods: a 51s start-up timeout (32–64s range) to accommodate system boot sequences, and a 1.6s nominal normal timeout (1.0–2.0s range) for runtime supervision. This is explicitly stated in the datasheet's Features section (Page 1) and Electrical Specifications (Page 7, Note 8).
What are the reset output configurations supported by the ISL88013IH529Z-TK?
The ISL88013IH529Z-TK provides complementary reset outputs: an active-high push-pull RST pin and an active-low open-drain RST/MR pin. As confirmed in the Product Features Table (Page 5), both outputs are present on ISL88013 devices, enabling direct interface with systems requiring either polarity without external components.
Can the ISL88013IH529Z-TK monitor a second voltage rail?
No, the ISL88013IH529Z-TK monitors only the VDD supply rail at its fixed 2.92V threshold. Unlike ISL88012/ISL88014/ISL88015 variants, it does not feature a VMON pin for adjustable secondary voltage monitoring. The Pin Descriptions (Page 5) and Functional Block Diagram (Page 4) confirm WDI is the fifth pin - not VMON - confirming single-rail supervision.
What is the minimum operating supply voltage for the ISL88013IH529Z-TK?
The ISL88013IH529Z-TK operates down to VDD = 2.0V per Absolute Maximum Ratings (Page 6), but its reset outputs remain valid down to VDD = 1.0V - a critical feature for fail-safe operation during deep brownout. This is explicitly stated in the Features list (Page 1) and verified in the Electrical Specifications table (Page 7, "Reset Output Voltage Low" test condition).
