The drivers • Dual Half Bridge MOSFET Drivers provide 3A of peak current for fast efficient switching • Integrated 100V Bootstrap Diodes and integrated high speed bootstrap diodes. Current sensing is provided by 2 transconductance amplifiers • Independent High and Low Driver Logic Inputs with externally programmable gain and filtering to • Bootstrap Supply Voltage Range up to 115V remove ripple current to provide average current DC information to the control circuit. The current sense • Two Current Sense Amplifiers with Externally amplifiers have buffered outputs available to provide Programmable Gain and Buffered Outputs a low impedance interface to an A/D converter if needed. An externally programmable input over • Programmable Over Voltage Protection voltage comparator is also included to shutdown all • Supply Rail Under-Voltage Lockouts with outputs. Under voltage lockout with a PGOOD Power Good Indicator indicator prevents the drivers from operating if VCC is too low. PACKAGE • SOIC-28 Typical Application Circuit 1 Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet. 2 All trademarks are the property of their respective owners.
