Selection Guide

external components. All devices in the family are identical except

for magnetic switchpoint levels.

The small geometries of the BiCMOS process allow these devices

to be provided in ultrasmall packages. The package styles available

provide magnetically optimized solutions for most applications.

Package LH is an SOT23W, a miniature low-profile surface-mount

package, while package UAis a three-lead ultramini SIPfor through-

hole mounting. Each package is lead (Pb) free, with 100% matte

tin plated leadframes.
