LTC1157CS8#PBF - Analog Devices

Description: 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
