A3230_06 Datasheet, PDF (2/12 Pages) Allegro MicroSystems – Chopper-Stabilized Hall-Effect Bipolar Switch

A3230
Chopper-Stabilized Hall Effect Bipolar Switch
Description (continued)
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°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.

1_{Pb-based variants are being phased out of the product line. Certain variants cited in this footnote are in production but have been determined to be NOT FOR NEW DESIGN.}
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.
