1 / 8 page 1 LTC1163/LTC1165 Triple 1.8V to 6V High-Side MOSFET Drivers S FEATURE s Operates from 1.8V to 6V s 0.01 µA Standby Current s 95 µA Operating Current per Channel at 3.3V s Fully Enhances N-Channel Switches s No External Charge Pump Components s Built-In Gate Voltage Clamps s Easily Protected Against Supply Transients s Controlled Switching ON and OFF Times s Compatible with 5V, 3V and Sub-3V Logic Families s Available in 8-Pin SOIC DESCRIPTIO The LTC1163/LTC1165 triple low voltage MOSFET drivers make it possible to switch supply or ground referenced loads through inexpensive, low RDS(ON) N-channelswitches from as little as a 1.8V supply. The LTC1165 has inverting inputs and makes it possible to directly replace P-channel MOSFET switches while maintaining system drive polar- ity. The LTC1163 has noninverting inputs. Micropower operation, with 0.01 µA standby current and 95 µA operating current, coupled with a power supply range of 1.8V to 6V, make the LTC1163/LTC1165 ideally suited for 2- to 4-cell battery-powered applications. The LTC1163/LTC1165 are also well suited for sub-3V, 3.3V and 5V nominal supply applications. The LTC1163/LTC1165 internal charge pumps boost the gate voltage 8V above a 3.3V rail, fully enhancing inexpen- sive N-channels for high- or low-side switch applications. The LTC1163/LTC1165 are available in both an 8-pin DIP and an 8-pin SOIC.
