H-Bridge Configuration
Zener Gate Protection
10 m Shunt Resistor
2 Linear Thermal Sensors, One For Each Bridge
Isolated Package
Output Currents Up To 20 Amps
DESCRIPTION
This series of MOSFET switches is configured as a Dual H-Bridge with common V
DD
lines, precision series shunt resistor in the source line, and sensing elements to
monitor the substrate temperature of each switch. This device is ideally suited for
Stepping Motor Control applications where size, performance, and efficiency are key.
