This classification indicates that sale of this device is currently restricted to existing customer applications. The device should not be purchased for new design applications

because obsolescence in the near future is probable. Samples are no longer available. Status change: May 1, 2006. These variants include: A3230ELHLT, A3230EUA,

A3230LLHLT, and A3230LUA.

diminished or removed, to ensure that the device switches, Allegro

recommends using magnets of both polarities and of sufficient

strength in the application.

TheA3230 is rated for operation between the ambient temperatures

–40°C and 85°C for the E temperature range, and –40°C to 150°C

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.
