Si1869DH Vishay Siliconix Load Switch with Level-Shift FEATURES PRODUCT SUMMARY VDS2 (V) 1.8 to 20 RDS(on) (Ω) ID (A) 0.165 at VIN = 4.5 V ± 1.2 0.222 at VIN = 2.5 V ± 1.0 0.303 at VIN = 1.8 V ± 0.7 DESCRIPTION The Si1869DH includes a p- and n-channel MOSFET in a single SC70-6 package. The low on-resistance p-channel TrenchFET is tailored for use as a load switch. The n-channel, with an external resistor, can be used as a levelshift to drive the p-channel load-switch. The n-channel MOSFET has internal ESD protection and can be driven by logic signals as low as 1.5 V. The Si1869DH operates on supply lines from 1.8 V to 20 V, and can drive loads up to 1.2 A. • Halogen-free According to IEC 61249-2-21 Definition • TrenchFET® Power MOSFETs: 1.8 V Rated • ESD Protected: 2000 V On Input Switch, VON/OFF • 165 mΩ Low RDS(on) • 1.8 to 20 V Input • 1.5 to 8 V Logic Level Control • Low Profile, Small Footprint SC70-6 Package • Adjustable Slew-Rate • Compliant to RoHS Directive 2002/95/EC APPLICATIONS • Level Shift for Portable Devices APPLICATION CIRCUITS 40 Si1869DH tf 35 2, 3 4 IL = 1 A VON/OFF = 3 V Ci = 10 µF Co = 1 µF 30 VOUT VIN Q2 25 C1 6 Time (µs) R1 6 20 td(off) 15 5 ON/OFF Co LOAD 10 Q1 5 tr td(on) 0 Ci 0 1 2 4 6 8 10 R2 (kΩ) R2 GND R2 Note: For R2 switching variations with other VIN/R1 combinations see Typical Characteristics Switching Variation R2 at VIN = 2.5 V, R1 = 20 kΩ COMPONENTS R1 Pull-Up Resistor Typical 10 kΩ to 1 MΩ* R2 Optional Slew-Rate Control Typical 0 to 100 kΩ* C1 Optional Slew-Rate Control Typical 1000 pF The Si1869DH is ideally suited for high-side load switching in portable applications.

These devices are intended for small to medium load applications where a miniaturized package is required. Devices in this package come in a range of on-resistance values, in n-channel and p-channel versions. This technical note discusses pin-outs, package outlines, pad patterns, evaluation board layout, and thermal performance for the dual-channel version. 6 5 96 (mil) 71 (mil) 48 (mil) 23 (mil) 61 (mil) 1 PIN-OUT 4 2 3 0.0 (mil) Figure 1 shows the pin-out description and Pin 1 identification for the dual-channel SC-70 device in the 6-pin configuration. Both n-and p-channel devices are available in this package – the drawing example below illustrates the p-channel device. 26 (mil) 16 (mil) FIGURE 2.

This pad pattern is sufficient for the low-power applications for which this package is intended. Increasing the drain pad pattern (Figure 2) yields a reduction in thermal resistance and is a preferred footprint. Document Number: 71405 12-Dec-03 8 (mil) SC-70 (6 leads) Dual EVALUATION BOARD FOR THE DUALCHANNEL SC70-6 The 6-pin SC-70 evaluation board (EVB) shown in Figure 3 measures 0.6 in. by 0.5 in. The copper pad traces are the same as described in the previous section, Basic Pad Patterns. The board allows for examination from the outer pins to the 6-pin DIP connections, permitting test sockets to be used in evaluation testing. The thermal performance of the dual 6-pin SC-70 has been measured on the EVB, comparing both the copper and Alloy 42 leadframes. This test was then repeated using the 1-inch2 PCB with dual-side copper coating. A helpful way of displaying the thermal performance of the 6-pin SC-70 dual copper leadframe is to compare it to the traditional Alloy 42 version. www.vishay.com 1 AN816 Vishay Siliconix Front of Board SC70-6 Back of Board SC70-6 S1 D1 G1 G2 D2 S2 vishay.com SC70−6 DUAL FIGURE 3. THERMAL PERFORMANCE Junction-to-Foot Thermal Resistance (the Package Performance) COOPER LEADFRAME Room Ambient 25 _C Thermal performance for the dual SC-70 6-pin package is measured as junction-to-foot thermal resistance, in which the “foot” is the drain lead of the device as it connects with the body. The junction-to-foot thermal resistance for this device is typically 80_C/W, with a maximum thermal resistance of approximately 100_C/W. This data compares favorably with another compact, dual-channel package – the dual TSOP-6 – which features a typical thermal resistance of 75_C/W and a maximum of 90_C/W.

TESTING Power Dissipation The typical RθJA for the dual-channel 6-pin SC-70 with a copper leadframe is 224_C/W steady-state, compared to 413_C/W for the Alloy 42 version. All figures are based on the 1-inch2 FR4 test board. The following example shows how the thermal resistance impacts power dissipation for the dual 6-pin SC-70 package at varying ambient temperatures. To further aid the comparison of copper and Alloy 42 leadframes, Figures 4 and 5 illustrate the dual-channel 6-pin SC-70 thermal performance on two different board sizes and pad patterns. The measured steady-state values of RθJA for the dual 6-pin SC-70 with varying leadframes are as follows: LITTLE FOOT 6-PIN SC-70 1) Minimum recommended pad pattern on the EVB board (see Figure 3).

In this example, a 174_C/W reduction was achieved without an increase in board area. If an increase in board size is feasible, a further 120_C/W reduction can be obtained by utilizing a 1-inch2.
