MAX16126/MAX16127 Evaluate: MAX16126/MAX16127 Evaluation Kits General Description Features The MAX16126/MAX16127 evaluation kits (EV kits) dem- Dual Circuits onstrate high overvoltage protection of the MAX16126/ Full-Featured Solution (-60V to +90V) MAX16127 devices for automotive applications that must Minimum Parts-Count Solution (0 to +60V) survive load-dump and high-voltage transient conditions. Robust Reverse-Battery Protection (Circuit 1) The fully assembled and tested surface-mount EV kit Positive Input Supply Voltage Protection Range board provides two circuits: One full-featured solution Extended Beyond +90V (Circuit 1) and one minimum parts-count circuit. The full-featured Adjustable Undervoltage and Overvoltage Thresholds solution exercises all the features of the devices and allows -60V to +90V protection beyond the 3V to 30V Adjustable Undervoltage Set for 8V operating range. The minimum parts-count solution pro- Adjustable Overvoltage Threshold Set for 32.1V vides a cost-effective option using a small 3A, dual Enable Input/Flag Output MOSFET and reduced 0 to +60V voltage range.
