GS2002 is a 3.3V output charge pump type voltage regulator chip, with a wide input voltage range of 6~28V and a maximum output current capacity of 150mA. It uses a fixed 900KHz switching frequency internally, and also integrates short circuit protection, overcurrent protection, overheating protection and other units to improve reliability. The ESD HBM can reach ± 6000V. Compared with traditional step-down chips, GS2002 does not require peripheral inductors and Schottky diodes, and its application scheme is simple, requiring only three peripheral capacitors. Meanwhile, due to the absence of inductive devices, the EMI of the chip is significantly lower than that of inductive switching power supply schemes, and it also has superior performance in output voltage ripple. Compared with LDO type voltage stabilizing chips, GS2002 has extremely high efficiency advantages. When the input voltage is higher than 10.5V, the conversion efficiency will double, and the maximum conversion efficiency can reach 81%. However, the output voltage noise will not increase too much, so GS2002 can directly replace LDO. Especially in the industrial fields of smart meters, water meters, and their communication modules, GS2002 is a voltage stabilizing power supply chip with superior cost-effectiveness.

GS1202 is a bidirectional relay driver chip used to control the operation of magnetic protection relays. The chip has a high output current and low static power consumption, and is widely used in the field of smart meters.

GS3016 is a line driver designed for narrowband power line carriers, particularly suitable for FSK or PSK modulation in power line communication systems. The chip adopts patented technology to achieve adaptive response to power line impedance changes, and can have high driving efficiency in a wide range of output load impedance changes. All input pins of GS3016 are logic pins, and FSK/PSK signals modulated by the system baseband can be directly input without the need for filtering. When the enable signal is turned off, the chip output is in a high resistance state. At the same time, the chip can also control the output mode under overload conditions. When the PE signal is pulled low, the chip will automatically switch to single end output under overload conditions to ensure that the system power supply is not greatly affected and maintain higher driving efficiency. GS3016 also integrates circuits such as soft start, over temperature protection, and over current protection, ensuring the chip has good reliability.
