Overview
EG12522 is a cost-effective half-bridge driver IC dedicated to dual-switch forward converter applications. It integrates logic signal input processing, level shifting, pulse filtering, and output gate drive circuits, specifically designed for dual-switch forward power supply topologies. The high-side operating voltage reaches up to 600V, with a wide low-side Vcc supply voltage range of 4V to 20V. The input channel IN incorporates a built-in 100kΩ pull-down resistor, ensuring both the high-side and low-side power MOSFETs remain off when the input is floating. The output current capability IO+/- is 0.8A/1.2A, housed in an SOP8 package. When the input logic signal IN is "0", the driver controls HO to "0" (high-side switch off) and LO to "0" (low-side switch off); when IN is "1", the driver controls HO to "1" (high-side switch on) and LO to "1" (low-side switch on). The IC employs a bootstrap floating drive supply architecture, greatly simplifying the gate drive power supply design — a single supply voltage VCC is sufficient to drive both the high-side N-channel MOSFET and the low-side N-channel MOSFET. The minimum bootstrap capacitance VC can be calculated using the following formula: VC ≥ 15 × (2 × [2 × Qg + Qperiod + (Ibso/F) + (Ibsc/F)]) / (Vcc - VF - Vds). Where: Qg is the gate charge of the high-side MOSFET; Qperiod is the charge requirement of the level-shift circuit per cycle, approximately 5nC; Ibso is the quiescent current of the high-side driver when turned on; Ibsc is the leakage current of the bootstrap capacitor; F is the operating frequency; Vcc is the low-side supply voltage; VF is the forward voltage drop of the bootstrap diode; Vds is the GS voltage required to fully turn on the MOSFET.
