Description

The MAX16945 ultra-small, monolithic, CMOS charge-pump voltage inverter accepts an input voltage ranging from +1.4V to +5.5V. This device features an ultra-low 12Ω output resistance, permitting loads of up to 30mA at +105°C with maximum efficiency. The MAX16945 operates at a frequency of 125kHz, allowing use of small external components. Its small external components, micropower shutdown mode, and wide temperature range make this device ideal for both automotive and industrial applications.

Oscillator control circuitry and four power MOSFET switches are included on-chip. The MAX16945 comes in a 6-pin SOT23 package and operates over -40°C to +105°C.
