• Manufacturer Part Number: sip42101dm-t1
• Description: Half-bridge N-channel Mosfet Driver For Motor Control
• Manufacturer: Vishay

Matched Propagation Delays
Rising and falling propagation delays are matched from PWM
to LX to within 8 ns.
Brake Input
When BRAKE is high, OUT
high to create active braking of the motor. When this input is
low, operation is normal.
Shutdown
The driver enters shutdown mode when SD is low. Shutdown
current is less than 1 mA.
V
MOSFET drivers draw large peak currents from the supplies
when they switch. A local bypass capacitor is required to

Undervoltage Lockout
Undervoltage lockout prevents control of the circuit until the

Thermal Protection
If the die temperature rises above 165_C, the thermal
protection disables the drivers. The drivers are re-enabled
after the die temperature has decreased below 140_C.
