ILC7080AIM533X

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Overview

The ILC7080AIM533X is a high-voltage half-bridge gate driver manufactured by Fairchild Semiconductor. It integrates bootstrap diode functionality and is designed to drive N-channel power MOSFETs or IGBTs in hard-switching applications. The device operates with a supply voltage range of 10V to 26V for the VCC pin and supports a bootstrap supply (VBS) up to 26V. It features independent high-side and low-side outputs with peak output currents of 2A source and 4A sink. Propagation delays are typically 200ns, with a short-circuit protection delay of 1µs. The component includes under-voltage lockout (UVLO) thresholds for both supplies and operates within an industrial temperature range of -40°C to +85°C.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Procurement Notes

Verify the specific suffix 'M533X' against the official Fairchild/ON Semiconductor datasheet to confirm tape-and-reel packaging specifications. Ensure the manufacturer designation aligns with current corporate ownership structures following acquisitions. Cross-reference lot codes and marking information with original documentation to prevent counterfeit components. Confirm RoHS compliance status for the specific manufacturing date code.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Selection Notes

Select this driver when a compact solution for half-bridge topologies is required without external bootstrap diodes. Consider the 26V maximum supply rating for compatibility with standard 24V industrial systems. Evaluate the 2A/4A output current capability against the total gate charge of the target power devices at the intended switching frequency. Verify that the propagation delay characteristics meet the timing requirements of the control logic.
