Product Details

The MAX14922 is a high-side, n-channel FET controller for implementing industrial high-side switches for switching ground-connected loads. The MAX14922 device controls an external nMOS power transistor, allowing low RON high-side switch applications from a +9V to +70V supply range.

Fast inductive load turn-off can be achieved with use of a high-voltage TVS diode enabling up to -70V (max) voltage clamping. Ground-connected TVS diodes allow clamping of exceptionally high inductive energies.

Load current is limited to a user-defined value through a sense resistor. External FET overload protection is achieved using an auto-retry timing feature, as defined by a user-selected capacitor (CBLANK at tBLANK input) or optionally using an external timing control.

The MAX14922 features an on-chip comparator enabling monitoring of the high-side switch output or the supply input voltage with a user-selected threshold. An integrated charge pump enables high speed switching rates when using low RON FETs in the 20kHz to 50kHz range.

The MAX14922 is available in a 3mm x 3mm, 16-TQFN package. The MAX14922 device is specified over the -40°C to +125°C operating temperature range.
