1. Product Information:

️· Product Name: IRS2153D(S)PbF
️· Type: Gate Driver IC
️· Package Options:
- 8-Lead PDIP (IRS2153DPbF)
- 8-Lead SOIC (IRS2153DSPbF)
️· Qualification: Industrial, MSL2 Leadfree

2. Key Features & Operation:

️· Under-Voltage Lock-Out (UVLO): Maintains a low supply current (<155uA) and prevents operation until VCC reaches the turn-on threshold. HO and LO outputs are low during UVLO.
️· Bootstrap Circuitry: Internal bootstrap MOSFET and capacitor (CBOOT) supply the high-side driver.
️· Oscillation: The oscillator frequency is determined by the equation:
f ≈ 1453 * RT * CT (Actual frequency may vary slightly)
️· Shutdown: An external circuit can pull CT voltage below VCTSD, halting oscillation and keeping LO low.
️· Normal Operation: Once VCCUV+ is reached, oscillation begins with LO activating first, then HO.

3. Supply Voltage & Startup:

️· Startup Capacitor (C VCC ): Needed to hold voltage above the UVLO threshold. Typically around 0.1uF.
