6 FAQs about [UC3842 Lithium Battery Pack Charging]

What is the UC3842B?

The UC3842B is a high performance, fixed frequency, current mode controller. It is specifically designed for Off-Line and DC-to-DC converter applications, offering a cost-effective solution with minimal external components.

What type of operation does UC3842 IC provide?

The UC3842 IC provides designers an inexpensive control- ler with which they can obtain all the performance advantages of current-mode operation.

What is the UCX842B?

The UCX842B is a high performance current mode controller available in 8-pin DIP, SOIC-8, and SOIC-14 packages. It has UVLO thresholds of 16 V (on) and 10 V (off), making it ideal for off-line converters.

What voltage does a uc3842 IC operate from?

FUNCTIONAL DESCRIPTION A block diagram of the UC3842 appears in figure 4. This IC will operate from a low impedance DC source of 10 V to 30 V. Operation between 10 V and 16 V requires a start-up bootstrap to a voltage greater than 16 V in order to overcome the undervoltage lockout.

Can the UC3842 safely drive a POWERMOS?

During UVLO, the UC3842 output driver is biased to a high impedance state. However, leakage currents (up to 10 µA) could pull high the gate of a POWERMOS if not shunted to ground. A 100 kΩ shunt, as shown in figure 6, will hold the gate voltage below 1V. APPLICATION NOTE 3/16

What package types are available for the UCX842B?

The UCX842B is available in an 8−pin dual−in−line and surface mount (SOIC−8) plastic package as well as the 14−pin plastic surface mount (SOIC−14). These devices also have separate power and ground pins for the totem pole output stage in the SOIC−14 package.
