Product details
Overview
PT8A3519BPE from Pericom Semiconductor is a dedicated smart electric iron controller IC with integrated shunt regulator, AC-line-synchronized timer (60Hz), 30s horizontal timeout and 10min vertical timeout, open-drain LED driver, active-high relay output, and buzzer tone generation at 4kHz. It enables automatic power cutoff in static positions for safety compliance in household irons.
For engineers reviewing the PT8A3519BPE datasheet, PT8A3519BPE pinout, PT8A3519BPE application, or PT8A3519BPE equivalent, key selection criteria include AC-frequency selection (60Hz), vertical timeout duration (10min), buzzer behavior (6-pulse stop), relay drive capability (5mA sink), and dual-package availability (DIP-8/SOIC-8).
Technical Context
The PT8A3519BPE uses AC line frequency (60Hz) as its primary timing reference via Schmitt-triggered ACCLK input, eliminating external crystal while achieving ±1% timer accuracy. Its sensor interface (SW pin) detects iron orientation through analog signal conditioning and debounce-resistant logic.
On-chip blocks include a 4.5–5.5V shunt regulator, system oscillator, power-on reset, and logic control that coordinates RELAY activation, DISC/BUZ 4kHz tone output, and LED flashing (1Hz post-timeout). All functions operate within -10°C to +85°C at VCC = 4.5–5.5V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Timer Accuracy | ±1% error using 60Hz AC line clock - ensures reliable safety cutoff timing without crystal |
| Vertical Timeout | 10 minutes - triggers relay deactivation when iron remains upright |
| Horizontal Timeout | 30 seconds - immediate heating cutoff if iron lies flat |
| Buzzer Output | 4kHz tone, 0.5s bursts ×6 then stop - audible alert confirming timeout event |
| LED Driver | Open-drain, 10mA sink - drives external LED with 1Hz flash during alarm state |
| Relay Drive | Active-high, 5mA source - directly interfaces standard 24VDC relay coils |
| Supply Voltage | 4.5–5.5V - regulated by internal shunt; supports 120V/240V AC systems via external circuitry |
Pinout & Package
PT8A3519BPE is available in Pb-free DIP-8 (PE) and SOIC-8 (WE) packages per JEDEC MS-001D/BA and MS-012E/AA standards.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| DISC/BUZ (Pin 1) | Output | Drives buzzer at 4kHz or discharges electrolytic capacitor; active-high |
| RELAY (Pin 2) | Output | Active-high relay control signal; sources up to 0.7mA to enable heating circuit |
| LED (Pin 3) | Output | Open-drain output; sinks up to 10mA to flash external LED at ~1Hz after timeout |
| GND (Pin 4) | Power | Ground reference for all internal circuits and external components |
| TEST (Pin 5) | Input | Low-active test mode entry; reduces timeout durations proportionally (e.g., 10min → 9.6s) |
| SW (Pin 6) | Input | Sensor movement/orientation signal input; high = horizontal position detected |
| ACCLK (Pin 7) | Input | Schmitt-triggered 60Hz AC line input; provides precise timing reference without crystal |
| VCC (Pin 8) | Power | 4.5–5.5V supply input; internally regulated by on-chip shunt |
Key Features
| Feature | Design Value |
|---|---|
| AC-synchronized timer | Uses 60Hz line frequency as clock source - eliminates need for external crystal or RC oscillator calibration |
| Position-aware safety logic | Distinguishes horizontal (30s cutoff) vs. vertical (10min cutoff) iron orientation via SW pin signal processing |
| Integrated shunt regulator | Stabilizes VCC at 4.5–5.5V from unregulated input - reduces external BOM count and improves supply robustness |
| Low-power standby | System current <400µA - meets sub-1W standby power requirement for energy-efficient iron designs |
| Test mode support | Pin 5 low enables accelerated functional verification - 10min timeout compresses to 9.6s for rapid validation |
Applications
| Household Electric Iron Safety Control | AC-Line-Synchronized Timer Module |
|---|---|
Use Scenario: Automatic power cutoff when iron is left unattended in upright or flat position. IC Role / Device Role / Timing Role: Primary safety controller executing orientation-based timeout logic using ACCLK-synchronized timer. Use Value: Eliminates risk of fire or surface damage by enforcing strict 30s/10min cutoff windows without software or microcontroller. | Use Scenario: Precision timing reference derived directly from 60Hz mains voltage. IC Role / Device Role / Timing Role: Hardware timer block synchronized to AC line frequency - no crystal or calibration required. Use Value: Achieves ±1% timing accuracy across temperature and voltage variations, reducing component count and cost. |
| Low-Power Appliance Standby Management | Buzzer-Enabled User Alert System |
Use Scenario: Maintaining safe, low-consumption standby state while monitoring iron position. IC Role / Device Role / Timing Role: System-level power manager with <400µA ICC and integrated shunt regulation. Use Value: Enables full compliance with <1W standby power regulations using only passive external components. | Use Scenario: Audible feedback upon timeout activation in noisy domestic environments. IC Role / Device Role / Timing Role: Buzzer driver generating 4kHz tone in six 0.5s bursts - distinct from continuous alarm. Use Value: Confirms safety event execution without visual confirmation; avoids nuisance alarms via finite pulse sequence. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar smart appliance safety controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| PT8A3515BPE | 8min vertical timeout instead of 10min; same 30s horizontal and 6-pulse buzzer | Used where shorter upright timeout is mandated by regional safety standards | Select when regulatory requirements specify ≤8min vertical cutoff |
| PT8A3517BPE | Same 10min vertical and 30s horizontal timeouts but continual buzzer (vs. 6-pulse) | Preferred in markets requiring persistent audible alert until manual reset | Choose when continuous alarm tone is required post-timeout |
Compared with PT8A3515BPE and PT8A3517BPE, PT8A3519BPE uniquely combines 10min vertical safety hold with finite 6-pulse buzzer feedback - balancing user awareness and alarm fatigue reduction in global iron designs.

FAQ
What is the function of the TEST pin (Pin 5) on PT8A3519BPE?
The TEST pin is a low-active input that activates accelerated functional verification mode. When held low, all timeout durations scale down linearly - e.g., the 10min vertical timeout becomes 9.6s - enabling rapid bench validation without waiting for full operational cycles. This mode does not affect normal operation when pin is left floating or pulled high.
Can PT8A3519BPE operate directly from 120VAC or 240VAC?
No - PT8A3519BPE requires a regulated 4.5–5.5V DC supply. External circuitry (e.g., resistive dropper + rectifier + shunt regulator) must derive VCC from either 120VAC or 240VAC mains. Application schematics in the datasheet show validated designs for both voltages using discrete components and a 24VDC relay coil.
How does the SW pin detect iron orientation?
The SW pin accepts an analog signal from a mechanical or infrared sensor assembly. Internal circuitry interprets high logic level as horizontal position (triggering 30s timeout) and low level as vertical (enabling 10min timeout). Signal conditioning includes noise rejection and debounce logic to prevent false triggers from vibration or transient sensor noise.
Is PT8A3519BPE pin-compatible with other PT8A351xB variants?
Yes - all PT8A351xB variants (B-series, 60Hz) share identical pinout, package dimensions, electrical characteristics, and functional architecture. Only timeout durations and buzzer behavior differ; no PCB redesign is needed when substituting between B-series parts like PT8A3515BPE or PT8A3517BPE.
