High speed, high throughput data transmission via USB interface has become a reality, significantly increasing

applicability. However, with increasing speed and functionality comes a price – greater power consumption, making

power switching a necessity. ROHM power switches are not only reliable and easy to use, they feature stable

operation and an energy efficient design.

Two types of thermal protection circuits:

Incorporation of an element structure in the switch

block that cancels the parasitic diode between

the input and output prevents reverse current from

flowing from the output to the input when the

ensures that the output is completely OFF

In conventional MOSFETs a parasitic diode exists between the

Drain and Source, allowing current to flow from the output to

the input, even when the MOSFET is turned OFF. ROHM’s 1ch

low output current USB high side switch ICs integrate a

structure that cancels the effects of the parasitic diode,

preventing reverse current from flowing when the switch is OFF.

USB High Side Switch ICsROHM’s 1ch large current USB high side switch ICs were designed for ON/OFF control of the USB line. A broad lineup is

offered, including the original BD6518FJ and BD6519FJ, along with the BD2051AFJ and BD2041AFJ that are pin-compatible

with many of the most popular products on the market.


Hot plug misdetection prevention due to built-in filterBuilt-in flag output delay filter prevents

false detection of hot plugging∗

An inrush current flows through the load capacitor whenever a

device is connected to the USB port. This current is

instantaneous but large enough to cause an overcurrent

detection error. Both the BD6518FJ, BD6519FJ BD2061AFJ,

and BD2065AFJ feature an overcurrent detection flag output

with built-in delay filter (2.5ms) that outputs a flag (warning) to

the CPU if overcurrent conditions persist after the delay time

has elapsed, preventing misdetection caused by inrush current.

Specifications

In a USB system, a 150µF capacitor is connected to the power supply output of the connector. If a

parasitic diode exists at the High side switch, when the power supply is turned OFF the output voltage

becomes greater than the input voltage due to the capacitor, causing a current to flow to the input terminal

through the parasitic diode.

ROHM’s High side switch, however, utilizes a configuration that cancels the effects of the parasitic diode,

preventing reverse current from flowing, enabling the system to turn OFF completely.

Automatic restore and latch OFF TSD circuitsTwo types of thermal protection circuits :

Latch and Automatic Restore

Two types of temperature protection circuits are integrated and

can be selected based on the application: an automatic restore

type that turns the switch back ON once the temperature

decreases below a threshold value, and a latch type that keeps

the switch OFF, even after temperature decreases.

Power management on a single chipConfigure power management switches easily

As notebook PCs and other compact, portable devices

increase in sophistication while becoming smaller and more

lightweight power efficiency becomes increasingly important in

order to prolong battery life.

Most of these devices typically incorporate various circuit

blocks and power supply systems that go into standby (idle)

state when not in use, reducing overall power consumption.

Conventional power management circuits are typically

configured using a number of components, including

PMOSFETs for switching, NMOSFETs for control, and CR

circuits to adjust startup times.

ROHM’s BD6520F and BD6522F integrate a low ON-

resistance NMOS switch and drive circuit into a single chip,

simplifying power management considerably. In addition, soft

start and load discharge functions, along with multiple

protection circuits, are built in, simplifying design while

ensuring a greater level of reliability.

Ultra-compact, space-saving package enables

The BD2270HFV is available in the compact HVSOF5 package

measuring just 1.6×1.6×0.6mm. This IC provides a significant

reduction not only in the number of external parts required, but

in mounting area as well – approximately 35% less than

comparable discrete configurations – making it ideal for

compact devices of all types.

Specifications

Smoothing capacitors are connected to the power switch output. Since the

electrical charge in the capacitors is initially zero, there is a considerable

amount of current flow (inrush current) when the switch is turned ON as

the charge builds up. As a result, the system could malfunction due to

operation of the current limiting/ low voltage reset protection circuits or

voltage drops along the power supply line.

ROHM’s power switch ICs suppress inrush current to the output capacitors

by turning on the switches gradually.

Built-in 3× step-up charge pump for gate drive

The voltage required for driving the NMOSFET Gate is generated by the internal

charge pump, which provides 3 times the voltage level of the supply voltage. In

addition, a capacitor is built in, eliminating the need for external components.

Output discharge circuit

The output discharge circuit operates when the AEN terminal is Low. During

operation the MOSFET switch (200Ω typ.) mounted between the DISC and GND

terminals turns ON. Connecting between the DISC terminal and source (load)

side of the NMOSFET enables immediate discharging of capacitive loads.

The AEN input is connected to a built-in hysteresis comparator, enabling control

via analog signals while facilitating sequence control for ON/OFF switching.
