Product Details

The MAX16128/MAX16129 evaluation kits (EV kits) demonstrate high overvoltage protection of the MAX16128/MAX16129 for automotive applications that must survive load-dump and high-voltage transient conditions. The fully assembled and tested surface-mount EV kit board provides two circuits: One full-featured solution and one minimum parts-count circuit. The full-featured solution exercises all the features of the devices and allows -60V to +90V protection beyond the 3V to 30V operating range. The minimum parts-count solution provides a cost-effective option using a small 3A, dual MOSFET and reduced 0 to +60V voltage range.
The EV kits can also evaluate various versions of the devices with different internally set undervoltage/overvoltage thresholds. Contact the factory to order different versions of the MAX16128 or MAX16129 devices and refer to Tables 2–5 and the Selector Guide and Ordering Information in the MAX16128/MAX16129 IC data sheet for details on device selection.
