Description and Applications

Features and Benefits

The DML10M8LDS is a single channel load switch with very low on-

resistance in a small package. It contains an N-channel MOSFET for

up to V_BIAS-1.5V input voltage operation and 6A current channel with

3.2V to 5.5V bias supply. The load switch is controlled by a low

voltage control signal through ON pin.

DML10M8LDS

Detailed Description

ON/OFF Control

The DML10M8LDS is enabled when the ON pin is on active high with 1.2V or above voltage. The device is disabled when the ON pin voltage is

0.5V or lower. The EN input is compatible with both TTL and CMOS logic.

VBIAS Voltage Range

For optimal on-resistance of load switch, make sure V_IN≤ 1.5V + V_BIASand V_BIASis within the voltage range from 3.2V to 5.5V. On-resistance of

load switch will be higher if V_IN+ 1.5V > V_BIAS. Resistance curves of a typical sample device at different V_BIAS= V_INat I_OUT= -200mA are shown as

below.

I_OUTvs. R_DS(ON)

I_OUT(A)

Applications Information

The basic DML10M8LDS application circuit is shown on Page 2. Component selection is explained below.

Input Capacitor

A capacitor of 10μF or higher value is recommended to be placed close to the IN pins of DML10M8LDS. This capacitor can reduce the voltage

drop caused by the in-rush current during the turn-on transient of the load switch. A higher value capacitor can be used to further reduce the

voltage drop during high-current application.

Output Capacitor

A capacitor of 0.1μF or higher value is recommended to be placed between the OUT pins and GND. The switching times are affected by the

capacitance. A larger capacitor makes the initial turn-on transient smoother. This capacitor must be large enough to supply a fast transient load in

order to prevent the output from dropping.

Thermal Considerations

To ensure proper operation, the maximum junction temperature of the DML10M8LDS should not exceed +150°C. Several factors attribute to the

junction temperate rise: load current, MOSFET on-resistance, junction-to-ambient thermal resistance, and ambient temperature. The maximum

load current can be determined by:

It is noted that the maximum continuous load current is 6A.

Layout Guidelines

Good PCB is important for improving the thermal performance of DML10M8LDS. Place the input and output bypass capacitors close to the IN and

OUT pins. The input and output PCB traces should be as wide as possible for the given PCB space. Use a ground plane to enhance the power

dissipation capability of the device.
