Si9978 - Configurable H-Bridge Driver

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.

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.

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 increased noise immunity.
