The MAX14736/MAX14737 overvoltage-protection (OVP) devices guard battery-powered modules in portable devices against overvoltage faults. The low 15mΩ (typ) on-resistance, as well as the low 13µA (typ) quiescent supply current of the devices, minimize power consumption, making them an ideal choice for low-power systems. Additionally, the devices feature a precision overvoltage-lockout (OVLO) threshold, ultra-fast response time, and surge suppression to ±35V, which serve to provide excellent protection against even high slew-rate, high-voltage transients.

The integrated power transistor in the devices is a p-channel device, but the intrinsic body diode from OUT to IN is removed through appropriate design techniques. Consequently, when the switch is in the off state, reverse-current blocking that is inherent to the devices. The MAX14736/MAX14737 feature a push-pull POK output, which is driven low if either an overvoltage, undervoltage, or thermal fault is detected; or if the device is placed into shutdown mode.

The MAX14736 has an active-low enable pin (EN), while the enable pin (EN) on the MAX14737 is active high.

When the enable pin is driven to the active state, the device is enabled. When driven to the inactive state, the device is placed in a low-power shutdown mode and the switch is kept in the off state.

The MAX14736/MAX14737 are offered in a small, 9-bump (1.34mm x 1.36mm) wafer-level package (WLP) and operate over the -40°C to +85°C extended temperature range.
