Product Overview
The MAX253ESA+T is a transformer driver for isolated RS485 interface in 8 pin NSOIC package. It is a monolithic oscillator/power-driver specifically designed to provide isolated power for an isolated RS485 or RS232 data interface. The device drives a centre-tapped transformer primary from a 5V or 3.3V DC power supply. The secondary can be wound to provide any isolated voltage needed at power levels up to 1W. It consists of a CMOS oscillator driving a pair of N-channel power switches. The oscillator runs at double the output frequency, driving a toggle flip flop to ensure 50% duty cycle to each of the switches. Internal delays are arranged to ensure break before make action between the two switches. The SD pin puts the entire device into a low-power shutdown state, disabling both the power switches and oscillator. It is used in high noise-immunity communications interface, isolated and/or high-voltage power supplies and bridge ground differentials.
- Supply voltage range is 2.5V to 6V
- Operating temperature range from -40°C to 85°C
- Shutdown supply current is 0.4µA
- Pin-selectable frequency of 350KHz or 200KHz
- Maximum on-resistance of switch is 4ohm
- Maximum operating supply current is 5mA
