MC34937APEK - Brand New Freescale / NXP Motor Drivers and Controllers
Credit Card - One-month free return and one year warranty.
- Full or Partial Refund, if the item is not as described
- Full Refund if you don't receive your order
**The 34937A is a field effect transistor (FET) pre-drivers designed for
three phase motor control and similar applications. The integrated circuit (IC) uses SMARTMOS technology.**
The IC contains three high side FET pre-drivers and three low side FET pre-
drivers. Three external bootstrap capacitors provide gate charge to the high
side FETs.
The IC interfaces to a MCU via six direct input control signals, an SPI port
for device setup and asynchronous reset, enable and interrupt signals. Both
5.0 and 3.0 V logic level inputs are accepted and 5.0 V logic level outputs
are provided.
Features
• Extended supply voltage operating range: 6.0 to 58 V
• Wide dead time range (50 ns to 12 s) programmable via the SPI port
• External FET gate drive capability of >1.0 A with protection
• Charge pump ensures sufficient external FET drive at low supply voltages
• Device protection against reverse charge-injection from CGD and CGS of
external FETS
• Integrated overcurrent, desaturation, and phase fault-detection
• Immunity against positive or negative transient voltage spikes on the gate
driver
• Current shoot-through protection built into dead time control
• Supports direct 3.3 V and 5.0 V logic interface to MCUs
• Integrated current sensing amplifier
• Device configuration and diagnostics through the SPI
