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 UA is a three-lead ultramini SIP for through-
hole mounting. Each package is lead (Pb) free, with 100% matte
tin plated leadframes.
