Variant is in production but has been determined to be NOT FOR NEW DESIGN. This classification indicates that sale of the variant is currently
restricted to existing customer applications. The variant should not be purchased for new design applications because obsolescence in the near future is
probable. Samples are no longer available. Status date change January 30, 2012.
diminished or removed, to ensure that the device switches, Allegro
recommends using magnets of both polarities and of sufficient
strength in the application.
The A3230 is rated for operation between the ambient temperatures
40癈 and 85癈 for the E temperature range, and 40癈 to 150癈
for the L temperature range. Two A3230 package styles provide
magnetically optimized solutions for most applications. Package
LH is a SOT23-W, a miniature low-profile surface-mount
package, while package UA is a three-lead ultramini SIP for
through-hole mounting. Each package is available in a lead (Pb)
free version, with 100% matte tin plated leadframes.
