... General Description The Infineon TDA21211 is a multichip module that incorporates Infineon’s premier MOSFET technology for a single high side and a single low side MOSFET coupled with a robust, high performance, high switching frequency gate driver in a single 40 pin QFN package. The optimized gate timing allows for significant light load efficiency improvements over discrete solutions ...

... Driver Characteristics The gate driver of the TDA21211 has 2 voltage inputs, VCIN and VDRV. VCIN is the 5V bias supply for the driver. VDRV is also 5V and is used to drive the High and Low Side MOSFETs. Ceramic capacitors should be placed very close to these input voltage pins to decouple the sensitive control circuitry from a noisy environment ...

... Enable GL= “Active” The TDA21211 driver includes gate drive functionality to protect against shoot through. In order to protect the power stage from overlap, both HS and LS MOSFETs being on at the same time, the adaptive control circuitry monitors the voltage at the “VSWH” pin. When the PWM signal goes low, HS, the High-side MOSFET will begin to turn off, after the propagation delay (T_pdlu). Once the “ ...
