MAX4845EYT+TW

Specialized ICS Overview

The MAX4845EYT+TW is an overvoltage protection controller designed to safeguard low-voltage systems against high-voltage faults up to 28V. It operates with a preset overvoltage trip level of 5.8V and features a low standby current of 10µA when the input voltage falls below the undervoltage lockout threshold. The device includes an internal charge pump to drive external n-channel FETs, eliminating the need for external capacitors. It provides a ±15kV ESD-protected input and offers an overvoltage fault FLAG indicator. The component is specified for operation within a temperature range of -40°C to +85°C.

Specialized ICS Procurement Notes

Verify the specific suffix TW against the manufacturer's official documentation to confirm tape-and-reel packaging details. Ensure the 6-UFLGA package dimensions match the design constraints. Cross-reference the 5.8V trip level requirement with system specifications before finalizing procurement.

Specialized ICS Selection Notes

Select this component when a fixed 5.8V overvoltage threshold is required for protecting low-voltage circuits. The internal charge pump simplifies the design by removing the need for external bootstrap capacitors. Consider the 6-pin ultra-thin LGA package size for space-constrained portable applications.

Specialized ICS Part Context

This part belongs to the MAX4843–MAX4846 family of overvoltage protection controllers. While other variants in the series offer different trip levels (7.4V, 6.35V, or 4.65V), the MAX4845 specifically targets the 5.8V threshold. The EYT+T suffix denotes the specific 6-pin ultra-thin LGA package variant.

Specialized ICS Replacement Considerations

Other members of the MAX484x family (MAX4843, MAX4844, MAX4846) share similar functionality but differ in their preset overvoltage trip levels. Verify that the 5.8V threshold of the MAX4845 aligns with the protected circuit requirements before substituting.
