MAX16945  
30mA Inverting Charge Pump in SOT23  
for EMI-Sensitive Automotive Applications  
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  
o AEC-Q100 Qualified  
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.
