Features

Low 35mΩ (typ) R_ON Load Switch
Ultra Low, 0.8µA (typ) Supply Current
Four Enable Inputs:
- TA: +28V (max) Capable
- ON_K: Accurate +3V Trigger Enable
- JIG: Factory Mode Enable
- S_EN: Logically ANDed with IN
Space-Saving 8-Pin, 2mm x 2mm TDFN Package
Controlled Turn-On to Limit dI/dt Pulses Due to Lead Inductance

Additional Details

The MAX14525 features a low R_ON 35mΩ (typ) load switch with four unique enable inputs. The MAX14525 is ideal for disconnecting the lithium-ion (Li+) battery from the loads in portable devices such as cell phones. The MAX14525 operates from a +2.2V to +5.5V supply voltage.

The MAX14525 features an extremely low 0.8µA (typ) quiescent supply current to maximize battery life in portable devices. It is enabled from four possible inputs: external charger connection capable of high voltage up to +28V, travel adapter (TA), on key (ON_K), factory mode enable (JIG), and switch enable (S_EN). The S_EN input is internally ANDed with the switched battery connection (IN).

The MAX14525 is available in a small 8-pin, 2mm x 2mm TDFN package and operates over the -40°C to +85°C extended temperature range.
