A6841EA-T

Overview

The A6841EA-T is a power distribution switch manufactured by Allegro Microsystems, designed for bipolar DC-DC conversion applications. It operates within a logic supply voltage range of 3.3 V to 5 V and supports data input rates up to 10 MHz. The device features CMOS and TTL compatible inputs and includes a power-on reset (POR) function. It is housed in an 18-pin PDIP package with dimensions of 22.86 mm x 6.35 mm x 3.3 mm. The component is rated for operation temperatures ranging from -40°C to +85°C.

Feature Summary

Provides space-efficient power switching for bipolar DC-DC conversions
Supports high-speed data input rates up to 10 MHz
Includes integrated power-on reset functionality

Applications

Bipolar DC-DC conversion systems
Power distribution networks requiring compact form factors
Logic-controlled power switching interfaces

Procurement Notes

Verify the specific suffix 'EA' against official Allegro MicroSystems documentation to confirm pinout and electrical characteristics. Ensure the procurement channel provides valid traceability for the PDIP package variant. Cross-reference the manufacturer part number with current datasheets to confirm active status or obsolescence before finalizing orders.

Selection Notes

Select this component when a compact 18-pin DIP solution is required for bipolar power switching. Verify that the system logic levels are compatible with the specified CMOS and TTL inputs. Confirm that the operating temperature range meets the environmental requirements of the target application, specifically noting the -40°C lower limit.

Part Context

This part belongs to the A6841 series of power management ICs from Allegro MicroSystems. The series focuses on efficient power distribution and control for industrial and automotive applications. The A6841EA-T specifically utilizes a through-hole DIP package, distinguishing it from surface-mount variants like the SOIC versions within the same functional family.
