Description
The MAX4838
MAX4842 are overvoltage protection ICs that protect low-voltage systems against voltages of up to 28V.
MAX4842 turn off the low-cost external n-channel FET(s) to prevent damage to the protected components.
Features
- include a 15kV ESD-protected input (when bypassed with a 1µF capacitor) and a shutdown pin (EN) to turn off the device (MAX4838/MAX4840/ MAX4842). All devices are offered in a small 6-pin SC70 package and are specified for operation from -40°C to +85°C. Features.
- Overvoltage Protection Up to 28V.
- Preset 7.4V, 5.8V, or 4.7V Overvoltage Trip Level.
- Drive Low-Cost NMOS FET.
- Internal 50ms Startup Delay.
- Internal Charge Pump.
- Undervoltage Lockout.
