The document introduces a self-oscillating half-bridge driver product with features including integrated 600V half-bridge gate driver, 15.6V zener clamp, and true micropower start-up.
The IR2153 family provides a high‑voltage half‑bridge gate driver with an internal 555‑type oscillator. It operates from a floating high‑side supply up to 600 V and includes a 15.6 V zener clamp on VCC, true micropower start‑up, and a shutdown pin that can disable both outputs.
Key features include tighter dead‑time control, low temperature‑coefficient dead‑time, increased undervoltage lock‑out hysteresis, and comprehensive ESD protection on all pins. The device is offered in 8‑lead PDIP and SOIC packages, with lead‑free and standard versions available.
| Maximum high‑side floating supply voltage (VB) | 625 V |
|---|---|
| Typical oscillator frequency | 20 kHz |
| Shutdown pin current (typical) | 1 µA |
| Maximum power dissipation (8‑lead DIP, Ta < +25 °C) | 1.0 W |
| Typical high‑level output voltage (VoH) | ≈ VCC |
The device can tolerate a high‑side floating supply voltage up to 625 V.
The oscillator typically runs at 20 kHz.
The CT pin current is typically 1 µA (0.001 mA).
The IR2153 is offered in 8‑lead PDIP and 8‑lead SOIC packages, with lead‑free versions also available.
