Working Principles

TLC7703IPWG4 operates by continuously monitoring the power supply voltage using an internal voltage reference. The threshold voltage can be adjusted using an external resistor connected to the TH pin. When the monitored voltage falls below the set threshold, the reset output is activated, indicating a power-related issue. The reset signal remains active until the voltage rises above the threshold or a manual reset is applied.

Detailed Application Field Plans

TLC7703IPWG4 finds applications in various fields, including but not limited to: 1. Automotive electronics: Ensuring stable operation of vehicle control systems during voltage fluctuations. 2. Industrial automation: Providing reliable reset signals for PLCs and other industrial equipment. 3. Consumer electronics: Preventing data corruption and ensuring proper initialization of devices during power-up.
