Overview

End of Life.
Last Available Purchase Date is 31-Dec-2014 Si9978 Vishay Siliconix Configurable H-Bridge Driver FEATURES H-Bridge or Dual Half-Bridge Operation 20- to 40-V Supply Static (dc) Operation Cross-Conduction Protected Current Limit Undervoltage Lockout ESD Protected Fault Output DESCRIPTION The Si9978 is an integrated driver for an n-channel MOSFET H-bridge.
The mode control allows operation as either a full H-bridge driver or as two independent half-bridges.
The DIR/PWM input configuration allows easy implementation of either sign/magnitude or anti-phase PWM drive schemes for full H-bridges.
Schmitt triggers on the inputs provide logic signal compatibility and hysteresis for inc...
