SGM4073
Reset Timer with Integrated Load Switch
GENERAL DESCRIPTION
FEATURES
The SGM4073 can be used as reset timer as well as
load management switch. The device is very suitable
for highly integrated applications.
Supply Voltage Range: 1.5V to 5.5V
Factory-Set parameters:
Reset Delay Time: 7.7s
Reset Pulse: 468ms
When the mobile device is turned off, press the start
key to keep the PMIC at a logic low level for 1.9s to turn
on the PMIC.
Turn-On Time: 1.9s
Turn-Off Delay: 7.7s
Adjustable Reset Delay Time
6A Maximum Continuous Current
20mΩ (TYP) On-Resistance at VBAT = 3.6V
Output Capacitor Discharge during Reset Period
Slew Rate or Inrush Control with tR: 3ms (TYP)
Enable Zero-Second Test
Since the Quiescent Current of the SGM4073 is as low
as 1μA (TYP), it supports direct interface with
low-voltage chipsets and can maintain low power
consumption.
When the device is used as
a
reset timer,
Available in a Green WLCSP-1.31×1.62-12B
Package
disconnecting the PMIC from the battery power for
468ms will produce a fixed delay time of 7.7s. The
delay time can be adjusted by an external resistor
connected between the DELAY_ADJ pin and ground.
APPLICATIONS
The SGM4073 also can be used as
a
load
management switch. It can disconnect loads with high
shutdown current and high load capacitance (< 200μF)
powered by a supply voltage lower than 6V. The
SGM4073 provides a 20mΩ on-resistance when VBAT is
3.6V.

ESD
This integrated circuit can be damaged if ESD protections are
not considered carefully. SGMICRO recommends that all
integrated circuits be handled with appropriate precautions.
Failureto observe proper handlingand installation procedures
can cause damage. ESD damage can range from subtle
performance degradation tocomplete device failure. Precision
integrated circuits may be more susceptible to damage
because even small parametric changes could cause the
device not to meet the published specifications.
