The LTC1157 dual 3.3V micropower MOSFET gate driver makes it possible to switch either supply or ground reference loads through a low RDS(ON) N-channel switch (N-channel switches are required at 3.3V because Pchannel MOSFETs do not have guaranteed RDS(ON) with VGS 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 Nchannel switch for 3.3V low-side applications. The gate drive voltage 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 3A standby current and 80A operating current, makes the LTC1157 well suited for battery-powered applications. The LTC1157 is available in both 8-pin DIP and SOIC.

0V VIN = 3.3V, CGATE = 1000pF Time for VGATE + 1V Time for VGATE = 5V, CGATE = 1000pF Time for VGATE + 1V Time for VGATE = 3.3V, CGATE = 1000pF Time for VGATE = 5V, CGATE = 1000pF Time for VGATE < 0.5V

The q denotes specifications which apply over the full operating temperature range. Note 1: Quiescent current OFF is for both channels in OFF condition. Note 2: Quiescent current ON is per driver and is measured independently.
