The MAX9065 is an ultra-small, low-power, window comparator ideal for a wide variety of portable electronics applications such as cell phones, portable media players, and notebooks that have extremely tight board space and power constraints. It comes in both a 4-bump UCSP package with a 1mm x 1mm footprint (as small as two 0402 resistors) and a 5-pin SOT23 package. The MAX9065 features a common-mode input range of -0.3V to +5.5V independent of supply voltage. The input current goes to zero when the MAX9065 is powered down (VCC = 0). Additionally, the MAX9065 features high RF immunity. The MAX9065 has a push-pull output and consumes only 1µA (max) supply current. The MAX9065 operates down to 1.0V over the extended -40°C to +85°C temperature range. Applications include cell phones, portable media players, electronic toys, notebook computers, and portable medical devices.
The MAX9065 is a tiny window comparator designed for portable electronics such as cell phones, media players, and notebooks. It operates from 1.0 V to 5.5 V, draws less than 1 pA supply current, and works over an extended temperature range of –40 °C to +85 °C.
The device is offered in a 4‑bump UCSP package (1 mm × 1 mm) and a 5‑pin SOT23 package. It features a push‑pull output, high RF immunity, and four hysteresis trip points for reliable voltage monitoring of single‑cell lithium batteries.
