The RICHTEK RT9709BGQW is an integrated circuit optimized for protecting low voltage systems from abnormal high input voltages up to 28V. It actively monitors input voltage, battery voltage, and charging current to ensure all parameters remain within normal operating ranges. The device also includes thermal monitoring, shutting down the MOSFET if chip temperature exceeds 140°C.
Key protection features include input over-voltage protection (OVP) that responds in under 1us, battery over-voltage (BATT OVP) protection, and over-current protection (OCP). The OCP threshold is user-programmable via an external resistor. The IC can also latch off permanently after 16 OCP events or battery over-voltage events, requiring power recycling to reset.
This IC is suitable for AC or USB charger applications and is housed in a thermally enhanced 12-WDFN (4x3) package. It operates across a temperature range of -40°C to 85°C (TA) and is surface-mount compatible.
Applications include cellular phones, digital cameras, PDAs, smart phones, and portable instruments.
