30mA Inverting Charge Pump in SOT23

for EMI-Sensitive Automotive Applications

MAX16945

General Description

Features

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 compo-

nents, micropower shutdown mode, and wide tempera-

ture range make this device ideal for both automotive

and industrial applications.

o +1.4V to +5.5V Input Voltage Range

o 30mA Guaranteed Output Current at +105°C

o Slew-Rate Limited to Reduce EMI

o 0.1µA Logic-Controlled Shutdown

o Low 12Ω Output Resistance

o Startup Current Limited

o 6-Pin SOT23 Package

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.

o AEC-Q100 Qualified
