Description
The UTC U3848/A/B/C is designed to provide several special enhancements to satisfy the needs: Power-Saving mode for low standby power, Over Current Protection (OCP), Over Voltage Protection (OVP), Over Load Protection (OLP), Over Temperature Protection (OTP) etc protection
Features
- IC will be shutdown when either protection arise and can auto-restart. Its frequency may be defined by user through resistor RT to external ground. UVLO featuring typical start-up current 20µA, and VCC(ON) 12.6V, VCC(OFF) 8.1 . Lower typical operation current Icc 3.7mA at inactive output. The output stage, suitable for driving N-Channel MOSFETs, can operate to duty cycles approach 70%. The U3848/A/B/C are fully pin-to-pin compatible with UC3842. But pin RT only connected a resistor to ground to.
