Product details
Overview
TLP5222(E from Toshiba Electronic Devices & Storage Corporation is a smart gate driver photocoupler designed for isolated IGBT and power MOSFET control in high-reliability industrial power systems. It delivers ±2.5 A peak output current, features integrated desaturation detection, active Miller clamp, soft turn-off, and under-voltage lockout (UVLO), and operates across −40 to 110 °C in a long-creepage SO16L package.
For engineers reviewing the TLP5222(E datasheet, TLP5222(E) pinout, TLP5222(E) application, or TLP5222(E) equivalent, this device supports critical safety-critical gate drive functions in photovoltaic inverters, UPS systems, and AC servo drives where high common-mode transient immunity (±25 kV/μs min), fast propagation delay (250 ns max), and reinforced isolation (5000 Vrms) are mandatory design requirements.
Technical Context
The TLP5222(E) integrates dual infrared LEDs with dual high-gain photo-detector ICs to achieve galvanically isolated signal transmission and high-current gate driving on the secondary side. Its internal architecture includes a linear amplifier stage stabilized by external 1 μF bypass capacitors between VCC2–VE and (if negative gate drive is used) VEE–VE.
Operation relies on precise timing coordination: DESAT leading edge blanking (1.4 μs typ.) suppresses false fault triggers during switching transients, while DESAT mute time (25.5 μs typ.) ensures reliable fault latching before automatic reset. UVLO thresholds (10.5–12.5 V) and hysteresis (0.4–1.4 V) prevent erratic operation near supply rail limits.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar isolated gate driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Si827x (Silicon Labs) | Digital isolator + integrated gate driver; lower peak current (4 A typ. but pulsed); no built-in DESAT comparator - requires external sensing circuit | Lacks monolithic DESAT function; suitable for designs already using discrete fault detection or where programmable timing is preferred | Select when digital control interface (SPI) and adjustable blanking are prioritized over analog DESAT integration |
| ACPL-332J (Broadcom) | Analog gate driver photocoupler; ±2.5 A output; includes UVLO and Miller clamp but no DESAT detection or FAULT feedback pin | No integrated fault reporting - requires external comparator and opto-isolated FAULT signal path | Choose for cost-sensitive applications where DESAT is implemented externally or omitted entirely |
Compared with Si827x and ACPL-332J, the TLP5222(E) uniquely combines monolithic DESAT sensing, isolated FAULT status, soft turn-off, and 5000 Vrms reinforced isolation in a single SO16L package - reducing component count, layout complexity, and qualification effort for IEC 61800-5-1 and UL 62368-1 compliant systems.

FAQ
What is the maximum recommended operating temperature for the TLP5222(E)?
The TLP5222(E) is rated for continuous operation from −40 to 110 °C ambient temperature. Derating applies above 90 °C: LED forward current decreases by −0.65 mA/°C and output IC power dissipation by −13.0 mW/°C. Thermal design must ensure junction temperature remains within absolute maximum limits per the datasheet's derating curves.
Does the TLP5222(E) support negative gate drive configurations?
Yes, the TLP5222(E) supports negative gate drive via dedicated VEE pins (9 and 12) and VE reference (pin 16). When VE – VEE > 0 V, a second 1 μF bypass capacitor must be placed between VEE and VE, with total lead length ≤1 cm. This configuration enables robust turn-off for IGBTs requiring negative bias to prevent spurious conduction.
How is desaturation detection implemented in the TLP5222(E)?
The TLP5222(E) implements desaturation detection via pin 14 (DESAT), which monitors IGBT collector voltage through an external RC network. The internal comparator triggers when voltage exceeds 6.0–7.5 V, with 1.4 μs leading-edge blanking and 25.5 μs mute time to reject switching transients. Fault status is reported on pin 3 (FAULT) and initiates soft turn-off.
What safety certifications does the TLP5222(E) hold?
The TLP5222(E) is UL1577 certified (File No. E67349), cUL recognized (CSA 5A File No. E67349), CQC approved (GB4943.1, GB8898), and VDE qualified to EN 60747-5-5 and EN 62368-1 - provided the D4 option is specified. Standard TLP5222(E) meets UL/cUL/CQC; D4 variant required for full VDE compliance.
What external components are mandatory for stable operation of the TLP5222(E)?
Two 1 μF ceramic bypass capacitors are mandatory: one between VCC2 (pin 13) and VE (pin 16), and - if negative gate drive is used - another between VEE (pins 9 or 12) and VE (pin 16). Total lead length per capacitor must not exceed 1 cm. Additionally, RDESAT ≥500 Ω and a Zener diode (e.g., CUZ8V2) are required on the DESAT pin for protection.
