Product details
Overview
ISL88013IH529Z-T7A from Renesas (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 systems.
For engineers reviewing the ISL88013IH529Z-T7A datasheet, ISL88013IH529Z-T7A pinout, ISL88013IH529Z-T7A application, or ISL88013IH529Z-T7A equivalent, key selection considerations include its fixed 2.92V VDD threshold, ultra-low 5.5µA supply current, reset validity down to VDD = 1V, immunity to supply transients, and compatibility with industrial temperature range (–40°C to +85°C).
Technical Context
The ISL88013IH529Z-T7A implements dual-reset architecture with push-pull RST and open-drain RST/MR outputs, enabling simultaneous reset signaling to multiple system blocks. Its internal comparator monitors VDD against a factory-trimmed 2.92V threshold with 29mV hysteresis, ensuring stable reset deassertion after brownout recovery.
Watchdog functionality uses an internal oscillator to enforce 1.6s timeout on WDI pin toggling during normal operation and extends to 51s during power-up, allowing safe OS/FPGA initialization without premature reset assertion. The device requires no external components for basic operation and supports manual reset via debounced RST/MR input.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDD Threshold | 2.92V ±1.5% - factory-programmed trip point for +2.9V rail monitoring with guaranteed accuracy over –40°C to +85°C |
| Supply Current | 5.5µA typical at 5V - enables battery-backed or low-power embedded systems to maintain supervision without significant quiescent load |
| Reset Validity | Down to VDD = 1V - ensures reset remains asserted during deep brownout, preventing partial logic state corruption |
| Watchdog Timeout | 1.6s nominal normal / 51s start-up - provides fail-safe CPU activity monitoring while accommodating boot sequences |
| Hysteresis | 29mV at 2.92V - prevents reset chatter near threshold due to noise or slow-rising supply rails |
| Reset Propagation Delay | 60µs max - guarantees fast response to voltage faults, critical for real-time safety-critical subsystems |
| Operating Temp | –40°C to +85°C - qualified for industrial-grade embedded control, instrumentation, and portable equipment |
Pinout & Package
ISL88013IH529Z-T7A is housed in a Pb-free 5-lead SOT-23 package (JEDEC MO-178AA, Intersil P5.064), measuring 2.9mm × 1.6mm × 1.1mm, with gull-wing leads optimized for automated assembly and thermal performance (θJA = 190°C/W).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - RST/MR | Combined active-low reset output & manual reset input | Open-drain output pulled low during reset; accepts debounced active-low signal for system-initiated reset |
| 2 - GND | Ground reference | Common return path for all internal comparators, oscillator, and output drivers |
| 3 - RST | Active-high push-pull reset output | Drives high (VDD) when not in reset; asserts low only during fault conditions or manual reset |
| 4 - VDD | Power supply and monitored voltage input | Supplies internal circuitry and serves as primary monitored rail with 2.92V threshold |
| 5 - WDI | Watchdog timer input | Edge-sensitive input requiring periodic toggle (rising/falling) to prevent timeout-induced reset assertion |
Key Features
| Feature | Design Value |
|---|---|
| Complementary reset outputs | RST (push-pull high-active) and RST/MR (open-drain low-active) enable direct interface to diverse logic families without level-shifting |
| Integrated watchdog timer | Dual-mode timing (51s startup + 1.6s operational) eliminates need for external RC timing network and reduces BOM count |
| Manual reset input | Debounced RST/MR pin accepts push-button or controller-driven reset with <1µs minimum pulse width requirement |
| Ultra-low quiescent current | 5.5µA max ensures minimal impact on battery life in portable applications and avoids loading sensitive power rails |
| High noise immunity | Designed to reject fast transients on VDD - prevents false resets during switching regulator noise or ESD events |

FAQ
What is the exact VDD reset threshold voltage for ISL88013IH529Z-T7A?
The ISL88013IH529Z-T7A has a factory-programmed VDD threshold of 2.92V with ±1.5% accuracy over the full industrial temperature range (–40°C to +85°C). This value is confirmed in the Electrical Specifications table on page 6 of FN8093 Rev 5.00, where VTHVDD for "IH529" variants is specified as 2.88V (min), 2.92V (typ), and 2.96V (max).
Does ISL88013IH529Z-T7A support watchdog timer functionality?
Yes, the ISL88013IH529Z-T7A includes a fully integrated watchdog timer with two distinct timeout modes: a 51s start-up timeout (to accommodate system boot) and a 1.6s nominal timeout during normal operation. This is explicitly documented in the datasheet's Feature list and Electrical Specifications section (Note 8), and applies specifically to ISL88013 and ISL88015 devices.
What are the reset output configurations supported by ISL88013IH529Z-T7A?
The ISL88013IH529Z-T7A provides complementary reset outputs: an active-high push-pull RST pin and an active-low open-drain RST/MR pin. This dual-output architecture allows simultaneous interfacing with both high- and low-active logic domains without external inverters or pull-up resistors on RST.
Can ISL88013IH529Z-T7A monitor a secondary voltage like VMON?
No, the ISL88013IH529Z-T7A does not support secondary voltage monitoring via VMON. Per the Pin Descriptions table (page 5) and Functional Block Diagram (page 4), ISL88013 uses pin 5 as WDI (Watchdog Input), not VMON. Only ISL88012, ISL88014, and ISL88015 feature VMON capability; ISL88013 is dedicated to VDD monitoring + watchdog + manual reset.
What is the minimum supply voltage required for ISL88013IH529Z-T7A to assert a valid reset signal?
The ISL88013IH529Z-T7A guarantees valid reset assertion down to VDD = 1V, as stated in the Features section (page 1) and confirmed in the Absolute Maximum Ratings table (page 6). This ensures reliable brownout detection even during severe undervoltage conditions before complete power collapse.
