TT2222 transistor

Description

This is 800V, 10A, NPN Transistor. The TT2222 is a robust NPN transistor engineered by Sanyo (now part of ON Semiconductor), primarily intended for horizontal deflection output in color CRT televisions.

1. Heatsinking is critical—with a 65 W dissipation rating, proper thermal management ensures reliability.

2. Voltage and current margins—the high V<sub>CEO</sub> and I<sub>C</sub> specs provide headroom, but stay within safe operating area (SOA).

Features

• High speed.

• High breakdown voltage

• High reliability (Adoption of HVP process).

• Adoption of MBIT process.

• On-chip damper diode.

BQ24727 datasheet

Description

The BQ24727 is a high-efficiency, synchronous battery charger, offering low component count for space-constraint, multi-chemistry battery charging applications. SMBus controlled input current, charge current, and charge voltage DACs allow for high regulation accuracies that can be programmed by the system power management micro-controller.

The device uses two charge pumps to separately drive N-channel MOSFETs (ACFET RBFET, and BATFET) for automatic system power source selection. SMBus controlled input current, charge current, and charge voltage digital-to-analog converters (DACs) allow for very high-regulation accuracies that can be easily programmed by the system power management microcontroller.
