The TPS22966 is a small, low RON, dual-channel load switch with controlled turnon. The device contains two N-channel MOSFETs that can operate over an input voltage range of 0.8 V to 5.5 V and can support a maximum continuous current of 6 A per channel. Each switch is independently controlled by an on and off input (ON1 and ON2), which can interface directly with low-voltage control signals. In TPS22966, a 220-Ω on-chip load resistor is added for quick-output discharge when switch is turned off.
The TPS22966 is available in a small, space-saving 2-mm × 3-mm 14-SON package (DPU) with integrated thermal pad allowing for high power dissipation. The device is characterized for operation over the free-air temperature range of –40°C to +105°C.

TPS22966EVM-007 — TPS22966-007 评估模块
TPS22966EVM 可让用户在不同的负载条件下（0A 至 6A）向两路输入分别施加 0.8V 至 5.5V 的输入电压。每个开关可由一个打开/关闭输入（ON1 和 ON2）单独控制，此输入可与低压 GPIO 控制信号直接对接。在该 EVM 上可监控输出、输入和开关波形。
TIDA-00513 — 用于提高输出电流和降低导通电阻的并联负载开关参考设计
TIDA-00513 展示了两个并联负载开关示例。通过在并行配置中放置多个通道，可以扩展现有负载开关的功能。
第一个示例使用双通道 TPS22966 的两个通道，总输出电流为 10A。
第二个示例使用三个并联的 TPS22959，总输出电流为 30A。
