LTC1157
3.3V Dual Micropower
High-Side/Low-Side MOSFET Driver
The LTC1157 dual 3.3V micropower MOSFET gate driver
makes it possible to switch either supply or ground
reference loads through a low R
DS(ON)
N-channel switch
(N-channel switches are required at 3.3V because P-
channel MOSFETs do not have guaranteed R

3.3V). The LTC1157 internal charge pump boosts
the gate drive voltage 5.4V above the positive rail (8.7V
above ground), fully enhancing a logic level N-channel
switch for 3.3V high-side applications and a standard N-
channel switch for 3.3V low-side applications. The gate
drive voltage at 5V is typically 8.8V above supply (13.8V
above ground), so standard N-channel MOSFET switches
can be used for both high-side and low-side applications.
Micropower operation, with 3
μ
A standby current and
80
μ
A operating current, makes the LTC1157 well suited
for battery-powered applications.
The LTC1157 is available in both 8-pin DIP and SOIC.
