Texas Instruments Integrated Circuits (ICs) - PMIC - Power Management - Specialized SN6505AQDBVTQ1

The SN6505A-Q1 is a low-noise, push-pull transformer driver designed for isolated power supplies in automotive applications, qualified to AEC-Q100 Grade 1 with an operating temperature range of -40°C to +125°C. It features a 1-A output drive capability at a 5-V supply, a maximum on-resistance of 0.25 Ω at 4.5 V, and an internal oscillator operating at 160 kHz. The device includes spread spectrum clocking for reduced EMI, current limiting at 1.7 A, under-voltage lockout, thermal shutdown, and a soft-start function to limit inrush current. It is packaged in a 6-pin SOT-23 (DBV) measuring 2.90 mm × 1.60 mm, with a junction-to-ambient thermal resistance of 137.7 °C/W and a shutdown current below 1 μA.
