strap and charge pump technique providing excellent switch-ing speed and steady state operation allowing the use of an N-channel MOS-gated power device as a high-side switch. This improves system efficiency, expands voltage range, and reduces the cost of the power device required. Overshoot Voltage Reduction Using IGBT Modules with Special Drivers. There is no practical charge pumps that allow to supply 20V to a high side switch with V ground offset. Charge pumps are more of a low voltage thing (I've seen them up to 60V bus voltage with few tricks to avoid reverse currents) but honestly I would not use them without reason above 24V bus voltage. By reason I mean, if you don't know just default to bootstrapping. Reviews: 1. 6 rows · Dual Rail High Voltage Gate Driver with internal charge pump for single or dual N-Channel.
High Voltage Gate Driver with internal charge pump for Back-to-Back N-Channel MOSFET. The LTC® is a fast high side N-channel MOSFET gate driver that operates from input voltages up to V. It contains an internal charge pump that fully enhances an external N-channel MOSFET switch, allowing it to remain on indefinitely. Its powerful driver can easily drive large gate capacitances with very short transition times, making it well suited for both high frequency switching applications or static switch. The MAX drives high-side, n-channel power MOSFETs to provide battery power-switching functions in portable equipment. The n-channel power MOSFETs typically have one-third the on-resistance of p-channel MOSFETs of similar size and cost. An internal micropower regulator and charge pump generate the high-side drive.
With a wide operating voltage range, high or low side MOSFET gate drive voltage can be optimized Internal Charge Pump Diode Reduces Cost and Parts Count. This gate driver circuit has six distinct blocks: the output drivers, MH and ML, low-side and high- side buffers, bootstrap capacitor based charge pump, low-. An internal charge pump boosts the gate drive voltage above the positive rail, fully enhancing an N-channel MOS switch with no external components. Micropower.
