9e102 — Datasheet

The IC includes a suite of robust internal protective layers to safeguard host circuit boards from catastrophic failure:

Without the full datasheet suffix, assume ±10% (K tolerance). If the original marking includes a letter after 102 (e.g., "9E102K"), the K indicates ±10%. J = ±5%, M = ±20%.

Bootstrap pin; connects a capacitor to the SW pin to drive the high-side N-channel MOSFET switch. Main input power supply rail pin (4.5V to 28V). 3
