LT1158

Half Bridge N-Channel

Power MOSFET Driver

FEATURES

DESCRIPTION

A single input pin on the LT^®1158 synchronously controls

two N-channel power MOSFETs in a totem pole conﬁgura-

tion. Unique adaptive protection against shoot-through

currents eliminates all matching requirements for the two

MOSFETs. This greatly eases the design of high efﬁciency

motor control and switching regulator systems.

Drives Gate of Top Side MOSFET Above V

Operates at Supply Voltages from 5V to 30V

150ns Transition Times Driving 3000pF

Over 500mA Peak Driver Current

Adaptive Non-Overlap Gate Drives

Continuous Current Limit Protection

Auto Shutdown and Retry Capability

Internal Charge Pump for DC Operation

Built-In Gate Voltage Protection

A continuous current limit loop in the LT1158 regulates

short-circuit current in the top power MOSFET. Higher

start-up currents are allowed as long as the MOSFET V

does not exceed 1.2V. By returning the FAULT output to

the enable input, the LT1158 will automatically shut down

in the event of a fault and retry when an internal pull-up

current has recharged the enable capacitor.

Compatible with Current-Sensing MOSFETs

TTL/CMOS Input Levels

Fault Output Indication

APPLICATIONS

An on-chip charge pump is switched in when needed to

turn on the top N-channel MOSFET continuously. Special

circuitry ensures that the top side gate drive is safely

maintained in the transition between PWM and DC opera-

tion. The gate-to-source voltages are internally limited to

14.5V when operating at higher supply voltages.
