SiP32458, SiP32459
Vishay Siliconix
20 m, Slew Rate Controlled Load Switch in WCSP6
DESCRIPTION
SiP32458 and SiP32459 are slew rate controlled integrated high side load switches that operate in the input voltage range from 1.5 V to 5.5 V. SiP32458 and SiP32459 are of P-channel MOSFET switching element with integrated gate pump that provides 20 m switch on resistance over a wide input voltage range. These devices have low voltage logic control threshold that can interface with low voltage control I/O directly without extra level shift or driver. A 2.8 M pull-down resistor is integrated at logic control EN pin. The slow slew rate of SiP32458 and SiP32459 in the range of 3 ms limits the in-rush current and minimized the switching noise. The SiP32458 features a reverse current blocking capability while the SiP32459 features an integrated output discharge switch. Both SIP32458 and SiP32459 are available in compact wafer level WCSP package, WCSP6 1 mm x 1.5 mm with 0.5 mm pitch.
